Here's a quick color comp that I did up in photoshop the other day before starting my drawing. This helped me to think more clearly about colors (though they will most likely change), and the general composition and pose. Sometimes I like to do this if I'm having trouble with an image.
...And this is my final drawing ready for printing and mounting. I couldn't get my photo to lighten up enough without washing out some parts. So to help, I did a little highlighting in photoshop to show where the lightest areas will be. I think I need to hit the face a little more just to give it that pop, since it's the most important part of the image. Any suggestions or comments are encouraged!
