Defintely clone out the limb lower right. This is a very nice shot. I think you can get more luminosity out of it with judicious levels and curves, though. It's worth a try. It's just shy of really singing.
Great shot. I agree with Rex about the limb on the bottom right hand of the picture. The color and exposure are really nice in this shot. Great nature capture.
Nice. I like it. Definately a print worthy shot. One thing I would change it to remove to one limb on the far right at the bottom. My eye was immediately drawn to that and I think you are after attention toward the waterfall.
