Here's one that I did just this week. Some sort of carnivorous snow devil. Not a literal devil, but definitely not human. I scanned in a medium detail pencil sketch and spent about 5 hours coloring it in photoshop. Once again I didn't use any reference, and it shows... I'm not entirely happy with the background. I also made some effort to use higher saturation in the foreground colors. I have a natural tendency to work low sat, low contrast.
