Since you didn't provide any details of your own on this photo, my critique will be short and simple...
I do see the 'rhythm' in the repeating patterns in this photo. However, I think the composition would be much stronger if you had tilted the camera to create some diagonals. The image would be more dynamic that way.
The lighting here doesn't work for me. The highlights are too bright for the theme, as I see it.
The brightness of the light seems to be outshining the leaves... perhaps too much contrast? Also, I think having the top leaflets a little more clear would help. Nice otherwise. :)
