Very pure, very stark - but perhaps more impact from those leaves is needed? I get, I think, your point; but find the lack of real definition (largely due to size) more of a stumbling block than an enhancement. One of the perils of the limits on image size, I fear.
Hmm.... is it interesting? Yes. The negative space makes it interesting. Is it something I would print and hang on my wall? Probably not... does that matter? I don't know. I'm going to score a 5 for now, but come back later and rethink this one.
