This is amazing, if I'm allowed to point something out without being negative I just feel it's a pity the two trees on the right are the exact same, giving away it's a photoshop. Cause it's otherwise flawless!
I wouldn't say it's flawless even apart from cloned trees. For example everything is in sharp focus including foreground and background, yet some parts of mid ground are out of focus (blurry) which doesn't make sense. Still a nice idea and composition though.
