Wowsers. LIke 3d man! Great dof, and nice color. I think compositionally, losing a bit off the left could make for a little bit stronger image. It does pop though :-) Nice job.
This is a cool shot, however, I'm afraid there is just a little too much glare on the flower. I polarizer would have worked well here to reduce the glare. Also, the background is a little distracting.
