the pencil version is very beautiful as well. I love his expression. Very mysterious. I would love to see this in a different technique. I bet it'll look great in a white paper done with an old inking/cross hatching technique.
So whimsical and magical. I love how the viewer can feel motion simply by beholding it. And I'll bet you didn't botch the gouache (though try saying that ten times fast!) -- I'd love to see what you do with it.
