To me, it looks like a close-up shot of a plant. Doesn't really have that 'impact' I feel. Maybe a little more post-processing should do the trick. Like have the main subject in colour and the rest in black & white, etc. Or you could have went lower to get it from a different angle which could have better emphasized your title.
Well generally it's ok but not very impactful.
I think the background is far too cluttered, and the overlapping green colour leaves make it hard for me to judge that your subject is really taller than the rest.
I would agree with MarkTan89's approach, go lower, and let the shorter plants fill the bottom of your frame.
personally, i feel that the aesthetic appeal is not present here. well, i just feel its not vivid enough- or at all to have any visual impacts on us. oh perhaps thats because i dont find typical plants in general a subject of interest. HOHO
