I like the dappled light, the color, the mostly dark background and the hint of branches in that background. Very simple but pleasing. I wonder if more could be done to reduce the effect of the red leaves exiting the frame to the right.
Very nice -- lovely composition with well-rendered reds! A bit more room on the sides and bottom would give it a bit more breathing room. It would be easy to burn down the brighter red part of the leaf in the BG on the right edge -- just a little.
A good quality image but from a compositional point of view I find it a bit awkward. The OOF leaves on the right keep taking my eyes off the main leaf. I am happy with the OOF branches in the background.
