I was wondering how much my art would be worth here on Menewsha. I have a variety of styles, and I only color in CG. Here are some examples.

I like the last one, I dislike the faces on the other ones, sorry.
But if you were to sell drawings like the last one, then I would have to say 300-gold-ish. The eyes are very pretty, so is the coloring. I would order some art from you if I had some gold left over after I finish my quest ^^

Okay, thank you

Any more advice for me?

no more advice? :(

Any more advice? Plox?

I say you could probably get up to 500 gold for something up at the top. Around 200 for headshots, 100 for sketch?
If you don't exactly know what to price your art as, I would make a "bribe" shop. You'll see patterns in the prices as people bribe for your art. So after you finish a few slots, make the average price permanent.
