A well-executed picture of a cute critter in action, which is all excellent, but I find it a bit frustrating to try to pick out the squirrel from the rest of the picture. The background is too similar to the squirrel in tonality (i.e. a background much lighter or much darker than the squirrel would work better), and a little too much of it is obscured by the foliage. The eye has to really search hard to find all parts of the squirrel, which is somewhat annoying. It's too bad, because otherwise I'd really like it. I understand that it can be difficult or impossible to find exactly the right surroundings when you're dealing with trying to capture a wild creature with a camera. Maybe you could try selecting the green background and changing its brightness (one way or the other) in photoshop?
