Nice, but a little blurry. Faster shutter speed needed, I think. It's a shame, because I've tried to take a similar shot on many occasions and it's not easy. You've caught the bee in the frame well, but it's just not sharp enough. Sorry.
I like the fuzziness of the bee, the blurr of the hard-working wings. It must have been hard to get as the bee wiggled the flower around. Ideally I'd love the flower, the all of the bee to be sharp - stoppped in motion. I'd also crop in closer to the bee and flower - from the top and the right.
