Your DOF is interesting because the leaf on the left is ALMOST in focus... I wonder if it is bugging anyone else? However, your subject is interesting and I like your composition (albeit the white leaf) Good work.
I think adding a blur to the leaf would help bring out the flowers. Just a small Gaussian Blur of maybe 2-4 px. I actually like the lack of color saturation in the image (at first I didn't, but after a few seconds of looking at it, I decided that it adds to the mood).
