Really interesting photo. It's amazing how near you seem to be to the squirrel when looking at this photo. As already said the leaf on the right is a bit distracting, but it probably wasn't possible to move that out of the shot without scaring the squirrel. Even though I like how big the squirrel is shown, I still fell like the photo is overall too small. It may be better to use a bigger field of view, with some more of the scene around the squirrel. I could imagine if the photo would show more of the background especially on the right and top of the photo it would create a even better photo, also the squirrel wouldn't be so much in the center of the photo anymore (but more in the bottom left corner).
