Most advice here is sound, but I'm going to solidly advise against copying what the popular adopt artists are doing.

Your followers follow you for YOUR work and the kind of things YOU enjoy-- if you're copying what others are doing, you may lose some of the "do what you enjoy" spark that evokes attachment and inspiration from your followers. I've seen really great artists with strong aesthetic sense throw it all out the window to make, say, kemonomimi despite never having been into drawing them before, and then get no buyers due to nobody following them being interested in it (not to mention; the market is already going to be saturated with people following the trend).

Don't be afraid to do what you've been doing! Sometimes niche is better to be honest!

• Auctions are a good way to gauge interest, but an OTA is nice because you don't need to set a deadline. Still be sure to set a minimum offer though.
• Share to enter raffles are a good way to gain traction; If you make a "batch" you can have one design be share to enter and the rest for sale, this is only if you struggle to get eyes on your work though
• Use toyhou.se's listing features, they help a TON
• Don't be discouraged if something doesn't get bought right away. It's okay for things to sit in you sales folder
• I would avoid discounting things too frequently; otherwise people may begin to expect it

Other than that, it really is a game of patience! Don't get discouraged, I cannot say that enough haha. Also,,, I am looking so hard....

i think you already have two of the biggest things that contribute to successful adopts - solid art skills and a following. like everyone else said the struggle would be they’re niche but i would say these designs seem like they could be used as non-pokemon …. i don’t know what the second one is LOL and the first one it took me a min to realize it was a pokemon. and as far a niches go, pokémon gininkas is a popular one 

also random side thought if you just wanna dip your toes in adopts more … food/desert inspired designs are always trendy so you could look there for inspired designs that have a market too. D&D characters are also trendy so maybe using random character generation for inspo for those 

Hi, I have a lot of experience selling adopts! It's become one of my main sources of income at this point. I gave some advice to someone in the forums a while back that you might find useful: https://toyhou.se/~forums/14421.help-questions/338453.adoptable-advice-?page=#post-5199445

TL;DR

• I agree with everyone below. 
• Put love and thought into every design (which you're already doing!)
• Copy what the popular adopt artists are doing. 
• Presentation is everything. Always write something interesting in the description regarding the adopts (personality idea, optional story, design notes, etc.)
• Don't give up!

I usually price my adopts cheaper than a custom or a commission, but you could always do auctions which will give you a pretty good idea how much your specific audience would want to pay for them! 

In terms of usage, I think it's important to have a TOS specifically detailing what your designs can and cannot be used for- especially when it comes to things like dating sims, video games, web comics, etc. It's also worth detailing whether or not you're comfortable with someone changing the design, editing them post purchase, or even paying you an extra fee to edit the design for them!

I'm terribad at explaining, but here's my TOS if you're interested in an example!

Getting into adopts can be rlly painful, I think with the scope of your audience you might not have a problem, but it is normal for designs to sit around for a loooong while before the right person comes around who wants it! vov My motto is not to throw away a design, even if maybe you don't feel it's strong enough or if it's not up to your tastes because there is someone out there who will love it as it is!

agree with the comment before mine - while i LOVE your designs i don't like having designs tied to a certain franchise too much. but i know there's definitely a community for gijinka adoptables! and, if you already have a bunch of them lying around, you can test the waters.

my advice would be:

- use tags and trade listings, they help get visibility out to users who aren't already following you

- start off with OTA (offer to adopt) or auctions rather than set price, and see how much people offer. you can set a minimum, but you might be inclined to sell your first few designs at a loss until you build an audience. a good incentive for higher prices is to offer extra art (ie. the reference sheets) ONLY if bids surpass a certain value!

- sometimes people will offer non-monetary goods and services, like art, characters, or other stuff. be upfront about whether you'll consider these or are looking for money exclusively - and make sure to state what payment mehods you use.

- take note of which of your designs sell better. you of course don't want to repeat yourself over and over, but you can look at it in broader strokes - does your audience prefer modern designs or more fantasy ones? do humanoids sell better than furries? this can help you narrow down your niche - although nothing stops you from trying new stuff every so often.

- write up a Terms of Service in advance. make sure to state what you are and aren't okay with people doing with your design - such as NFTs, commercial usage, trading, reselling, etc. it's also used to list users you don't want to have access to your services, like a blacklist. while TOS are not legally binding, most of toyhouse users respect and obey them based on a honor system, and if you need to file a dispute, toyhouse staff will be more likely to take your side if you can provide your TOS.

- lastly, don't get frustrated if you take some time to sell designs, or if your designs don't seem to be used after you sold them! this one's more of an emotional thing, but sometimes it takes time for the one person who'll cherish your design most to find it. i've had designs ( both mine and others) sitting for sale for months until the right person contacted me wanting to buy. it happens to all of us! patience is key.

i hope these help! I'm not a popular designer by any means, and my niche is very, very different from yours ( cartooney ) but these are tips i wish i'd heard before jumping into selling adopts.

Strictly my own opinion ofc, while I think gijinka adopts are very popular, sometimes they feel limiting in how they can be used as an OC. I personally have a hard time justifying some gorgeous gijinka out there because I just dont know what I would do with them. That said, your gijinka are gorgeous and Ive always adored your misdrevious and suicine designs. Im sure you would have zero issue with finding people to buy designs like that and if you're just looking to rehome some fun exercise characters, you'll be absolutely fine

An alternative could possibly be moodboard adopts? Buyers offer presenting moodboards instead of OCs. Or those emoji adopts where you or the buyer just play with a series of emojis and see what comes of it? I've seen a lot of popularity with both of those.

Price wise, Im not sure what would be best to suggest. You're still putting out very high quality art, so definitely don't undersell yourself. I've seen some people charge a lot more for adopts than I myself am usually up to paying at the same time people are fighting each other to lay claim first. I find it easier to spend more on commissions of characters Im already attached to over new concepts, but that's a me thing. If you're unsure about prices, auctions are typically pretty successful and can possibly help narrow down your range

Usage you definitely want to kick NFTs and AI usage in the ass from the get go, and probably want to include some sort of personal vs. commercial use for designs. Those would be the biggies I can think of

Hope my rambling here is a little bit helpful! I look forward to seeing what you do next!
