under painting

I didnt the under painting for the sculpture. The problem is I'm not sure how to do the over painting so it looks good. right now it's too flat to leave it, but I'm nto getting fine enough control out of either hte acrylics or the brushes I've had. I've never been good with very small brushes, so I'm a little stymied.

I also did this to my arm. Not terrible artistic, but fun none the less.
