I've just joined the site yesterday but doesn't seem to be many people looking for art. This is something I just drew of my avi, how much would you pay for it?

And if I were to open a shop and actually draw clothes and stuff on it, then how much should I price it at?

I really need help, art is the only way I'm good at earning gold

i would say you could get anywhere between 400-500g for something like that with or without clothes :P
but you could also try doing a bribe shop and see how that goes

I would pay 800 for it with clothes, and I love art, maybe I'll hit you up if you open a shop ;)
