Here is a perfect example of overpainting. Keeping in mind the left half is supposed to be front and the right half is supposed to be a back you can see fairly clearly which I spent more time on. Even though I fussed over and repainted and overpainted the left side still did not get any better than the right. I spent what seemed to be an hour on the left and less than five on the right. (the drawing was already done) With the drawing intact on the right it looks far better to me. OH well its good practice and a lesson learned.
