I do tend to prefer off-centering the 'attention object' (being the flower in this case) in most photography. I think I'd like it better if it had less to the right of the plant but to each his own. It is a very beautiful photo!
Good choice of color gradient, and I like the perspective on the plant - anthropomorphizes it somewhat. The bottom edge feels a bit awkward, though, since there's the two bits in focus in the center & left that sorta pull attention away from the rest of the plant. Maybe if it was cropped a bit higher?
