Welcome to Gaia! ::

I really like your style, they are super cute.. but, huh. I'd say you could probably set your prices (headshots, at least) 5k each. But, if you expand the headshot thing, most likely more.

I wouldn't price them too high at first, 5k, like the others have said, might be a good price to start with, depending on how much time you take on each. If it's something you can do in minutes (and because it's digital, no resources are being used up) then I'd lower the price.

Also, I'd draw a little more of the avi into the head shots, just to make it look more balanced. Like, a bust more than a head shot unless you're willing to do something exciting with the shoulders or if it's from a different angle.

I like the style though, very much. Bold lines are great for chibi things so you've definitely got a good style for this and I think if you were to sell art you'd do well.
