Oftentimes I see the great debate; commissioners want cheap art, other artists are furious at cheap art because then their art can lose value. I see both sides of the coin, but personally if I raise my prices above maybe $8 for a fullbody, I almost never get commissions. Many people tell me I should be charging no less than $15-$20! As much as I would love to get that much considering a fullbody of a medium complexity character may take two hours or so, I just don't think I could actually get anyone to buy. What are your thoughts / opinions?

For relativity, here is my current price list.
Colored Sketches-
Headshot: $2.50
Halfbody: $4.00
Fullbody: $5.75
Custom Design: $10

Finished:
Headshot: $5
Halfbody: $8
Fullbody: $11
Custom Design: $15

Feral references only for now, will include both sides and pelt top and bottom views, as well as some accessories and a headshot if they are excessively complicated. They are available for $18
