these are really awesome, great face anatomy. I especially like the logo on the lion head.
Also, freelance art is pretty easy/simple to manage, as long as you have a reliable scanner. Check out /r/artshop, become active within DeviantArt, or perhaps find a niche in a smaller community. I sell through
GASR, an IMVU-based art community. The demand for art is high in IMVU, so it's pretty easy to sell, especially if your art is realistic. I do digital art there and it pays like a minimum wage job (well used to, I've been busy since summer school started)
