Like 40-50 dollars per character

30-50 per character. 30 being cheap while 40 being more average. 50 I think would be expensive and to much.

Generally I'd say do some YCH or OC adopts for 20-30$ starting bid and see how much auctions of those go for with a the bid ending 24-48 hours last bid. Will give you a possibly base estimate in interests of price. Though it's all going to be based on how often you want commissions and such, often popularity plays a big factor so doing more for less is always my suggestion.

Same thing as said before, 40 dollars would be good, even if it's always hard to tell a price when you're not an artist (well for my own)

yeah. definitelly in the range of 50$ per character + an extra for complex background. Also depend on how much work you would put into this level of resolution, if i may know

that would be about 40-60 ish. It really makes me want to commission you again ><

I'd say around the 35 to 60 dollar range
