That's a very nice picture. I wonder if there is a way to tone down some of the red in the limb closest to the camera. It draws my attention away from the squirrel.
hehe Nice I like it
If you want to reduce the reds in the tree use a selection brush and select that area of the photo then edit the Hues and saturation for that area. In the saturation menu you should have an option where it says master and then a dropdown where you have more colour options - just select red and then desaturate it (making sure not to take it too far that it looks strange)
