Very nice macro study. And the "expression" of the bee's face is one of "back off." Sharp details of the bee and surrounding flowers. The only things I would have changed are the bright background in the upper right and remove the spider web but with a mean bee like that, I can understand why you didn't. :) Also the border is a bit thick. 7
LOVE the expression on the bug. Bet that took a few tries! The hue and saturation of the bug and the buds is very similar. I lose some of the bug. Not much you can do about it however. Hope this does well. good luck.
cool shot, like the shallow DOF. too bad the upper right corner is blown out. if it wasn't for that, the whole picture could use a little more brightness - I'm looking at it on a very bright screen and it still looks rather dark.
