Really impressive view. I really like such a close up. The only suggestion I would make and it could just be my opinion, would be to close down the f-stop a bit for a little more depth of field within the flower. But seriously, I do really like it.
nice detail. Something strikes me as harsh about this picture. I don't think it's the colors, but more the lighting. But the technique and DOF are very nice.
I'll confess I like this photo the way it is, with its seven points of focus over an out-of-focus background. My only comment would be to wonder if this photo might look even stronger if it was square, dramatizing the radial symmetry with equal margins on all four sides.
