Whoa, you're awesome!
How long have you been drawing? Are you self-taught? Beautiful shading, way to go! I love that Amy Lee portrait, and the horse is amazing.
You should check out my stuff, too, when I can figure out how to post it on the darned thingamajig. My user name should have been, "Mechanically Hopeless."
Keep up the great work--post more goodies!
