Hello! My dear friend wants to start selling some of his drawings here and we need some help with the pricing. He intends to do mostly furries and pets.

Examples: x | x | x

He doesn't have a good shaded version of an example yet, but he is capable of shading - so, what do you think would match for pics like that? How much would be flat colored, how much shaded? Is it even worth it selling für USD? We appreciate any advices you can give us.

Also, if someone is already interested, the ping group:
