Design Terms of Use
Standard rules:
Don't resell for more than you bought it without extra art (you can create art for them yourself or commission but be reasonable and go with the prices that you do/would do for commissions)
Credit me
You can redesign all you want but if the design is closed species abide by the rules of the species
Would love if you asked me questions on what you can do with them and what you can't instead of just assuming since I can't think of anything else to put here :P
Enjoy the design and thank you for buying/trading/etc <3
