This is an amazing shot. Catching bees in mid-flight is definitely not easy to do., that in itself deserves high marks. The butterfly is a beauty. It's just a pity that the butterfly and the second bee (to the left) is out of focus. The main focus of the image is obviously the butterfly , but only the bee in the right is fully in focus.
Aside from that, well done. Luck like this is hard to come by,
