Color Sketching

I spent a good part of the day inking two pages of Perils On Planet X, that I decided to play for about an hour and just sketch. But then decided to do a color sketch. So with a piece of 12" x 18" watercolor paper, a pencil and some fluid acrylics I did this. Just a bunch of trial and errors tied up in one piece. It was fun to just let loose after all that precision inking. :)
