I do like the diagonal created by the whole flower. The detail on the leaves to the left is wonderful. I like how the sharpness of the subject makes it stand apart from the background. Congrats on your top 3 score!
very crisp editing. The uniformly sharp subject almost makes it look 2 dimensional. You must have had good seperation from the background to be able to acheieve this. :) Maybe a closer crop would help the image to get rid of the extra leaves and clutter on the left.
