Very strong shadows, seem oo black to me, a little unnatural which is probably the effect you were going for but for me that strong black overwhelms the main subject a little. Nice strong graphic shape though.
Subject = great. Exposure = right on. Lighting = ok - but mabe a bit softer would be better (the shadows are very black.) Composition: Would be much stronger taken on a diagonal. Prognosis = well high in the pack.
I had this idea too. Fortunately, I submitted something else, yours is very good. The white background contrasting with the black shadows gives it a strong impact. I probably had tilted a bit the leaf to lead to a more diagonal view.
(hope my English is understandable :)
