The most interesting part of the photo I think is the upper portion where the pattern of lines goes one way then the other... I wonder if it would look better if it didn't keep coming forward quite so far. I might make copies and play around with some different crops (not necessarily huge, seems like someone says 'crop' and people whack off way too much! lol) and see how it might look with a little less foreground (where the leaves more close up seem to get larger). Judgement call I think on how you balance one set of lines with the other and how much or how little to have in the frame.
I'd adjust the contrast too, to get a 'black' black and a 'white' white with a range of grays in between.
Very nicely done. Keep at it, you definitely seem to be on the right track.
