Interesting concept, although an overzealous use of the smudging tools. Also, I’m not really sure where you were headed with the character design, but the anatomy just doesn’t feel very solid… maybe you were going for something more abstract, I don’t know. On that same note, physically speaking his eyeball should be falling out of it’s skull since there is nothing supporting it underneath or on the side, but it could be that you’re going for the more cartoony googly-eye thing.
Either way, keep at it… practice really does make perfect.
