Because I have had to see my Free to Use sprites parts being sold for over 10$ now I feel like I have to say this even though I though it was a given. Do not sell adopts you made with my parts for that much money they are free to use for everyone and unless you hand made all the other parts I ask that you don't charge an obscene amount of currency for them. [Keep it within the like 300-500 point maximum unless it's an OTA and someone offers that much but don't make over that much the minimum amount.]
If you're offering extra art or the character comes with more art then of course by all means charge what you feel it's worth but JUST the sprites is a bit ridiculous. I try to make it so people can enjoy my sprite parts and make them as available to people as I can. I do make these for fun as a side project whenever I get the chance and are by default not even that super quality as some of the other artists here so please I wouldn't even charge those kinds of prices and I made them.
