Well, I've seem similar go for about 500-600K for the anime, and 150-250K for the chibi. I would suggest you open a temp bribe shop and see what sort of offers you get.
Would you please price me back? And here is a WIP, if you need another example.
*- thats the base price of your art. with commission, it will reach 1mil. HD quality still applies for price increase.

Wow. The artwork's really good. I actually can't price, was inactive on Gaia too long. But I remember you could get good prices by looking in the art request threads, for the people that advertise how much gold they have to buy with.
