I think I get that nature and man are often in conflict (by man's choice) but I don't think that comes through in the photo - I don't see the conflict illustrated. I like the composition and the use of monochrome vs. color.
I love how the leaf looks like it is just floating on the hand. Love the details and lines of the hand. I am curious tho as to why some parts are either softened or blurred?
I'm not sure whether you've selectively blurred or just used an incredibly shallow depth of field, either way I do find the blur a little too much though it undoubtedly brings the leaf to the fore and emphasises its outline. A nice and simple use of selective desat and a powerful concept well illustrated.
I really wish the texture in the palm had been better preserved. this is a beautiful image but the rrandom spots of smoothing just don't seem to fit in
