Usually FA is a little more realistic with prices than DA. I was wondering how much you guys would say you would pay for a fullbody commission of mine? Size ranges from 8 x 10 to 9 x 12 (slightly bigger than A4) depending on what the person wants. I'm trying to fix new commission prices. Should I give base prices, or a fixed price?

Prices are for a single character, no background by the way!

Thank you for any and all input!
