It's a bit too soft for my taste, though I like the centered comp with the flower, and the square crop. Different subject would have done better with the softness, perhaps.
Centered composition works well here. Is this an outtake from the soft focus challenge? I'm not so sure I like the blur, I love to see macros really sharp.
A possibly good image ruined by too much blur and the funky vignette. I think had the flower been sharp and the vignette left off this would have been a stronger image.
Nice soft focus shot and well presented for a centered composition. A bit of detail is lost in the petals (and very hard to keep!) which may knock it down in score a bit. The light vignetting around the edges does bother me just a bit - makes me want to put on my glasses, whereas the soft focus of the flower itself is just right.
