The Dragon's out of the bag...

Today I want to share with you a sketch I worked on last night while playing Dungeons and Dragons, it's based on a concept my husband shared with me nearly a week ago.  I'm doing things a bit differently today because I'm going to show you the initial sketch, the lineart and the coloring.  I wanted to keep this one very, very simple with the shading.  I wonder if I oversimplified it though, maybe I should add a little more shading...thoughts?
