Great picture! My only complaint is that Totoro looks a bit more cartoonish than normal. Then again, I guess Miyazaki's films are more cartoonish than most anime. I do like how adorable he looks! He actually seems to be less happy than normal. It's still a great environment.
The leaves are a wonderful touch. They just seem to be like they're part of some single entity in this. In fact, most of the background is really fluid. The mushrooms grow up so perfectly. The berries are great too.
