I like the photo, but I think you may have used a little too much NeatImage? Just a guess - but it distracts a bit, from an otherwise very interesting shot.
Looks like your original capture was very good, but the postprocessing has just about ruined it. Don't know if it's compression artifacts or some combo of sharpening and noise removal, but whatever it is it left massive artifacts all over the flower and bee.
The composition in this is nice, as well as the limited DOF. The entire image lacks the detail that you would expect from a macro shot. It almost looks as if it was neat imaged quite a bit.
