Shot this bee and flower with a Canon 100-400 & Canon 500D Close-up filter. Ambient light set at -2 and flash set at -1/3, 1/30 sec, f8, ISO 100, hand held.
Rich colors and great details on the bee & flower! I like the comp - you have a good position on the bee and the flower so both fit well in the image.
Only thing I might suggest would be to tone down the flash markings in the places where they go to white hot. I don't know that I'd eliminate them altogether...maybe just tone them down a bit so they blend with the rest of the bee better.
