Sketch and digital painting

Thought I would give digital painting a shot.  Although I used mainly conte crayon and charcoal brushes so you could say it's technically not a digital painting.  I found the original picture in this great close up gallery.  I then drew the lizard in my sketchbook and scanned it to begin the "painting".  I realized to late that his chin is a bit to long and he looks more like a komodo dragon than a little gecko, oh well.  From sketch to finished image took about 3/3.5 hours.  I wanted to keep going but I stopped myself.  Sometimes when I sketch, I try to make it just a little bit better and it looks overdone. Hope you enjoy.
