This one is a newer one I've been experiencing as a seller, but asking for commissions of a character you haven't secured yet,, you may be paying them off, but I'm not about to get into some drama about cancellations, late fees etc. Please for the love of god, give me a character you own, unless it's a gift.
As a buyer, when people don't,, list their examples as images in their posts? I know you want to keep it clean, but at least have thumbnails,, to me it always seems lazy or uncaring to just say "look at my deviantart" or "heres an imgur list", just,, put?? the?? examples?? in the post?? As a seller who has the perspective of buyers, people are usually not willing to click through a million links to get examples. Hell, just put one good example and a list beneath it- at least then people have a good idea of your style instead of it being a wildcard.
