I like the mix of white and green, they are very contrasting and complimentary colors. Edges are a little soft but it's quite an abstract image that I think it doesnt really matter. I would have liked to have seen a little more vibrant color, but white is so hard to get vivid without losing some details. The shadow on the petal is a little bit distracting, but not overly so. I like it.
I think this is a very good photo. I assume the soft look was intentional so I won't say "it could be sharper." However, I think I would like it a little better if you could have captured it without the shadows as the white between the flower and the stamen is a little blown out. All in all I think this is a very good photo though.
Quite a lovely shot. I like the composition, and that I can see just the hint of the flower fading into the background. Not crazy about the shadows in the flower itself, would like to have seen more light filling those shadows in.
Lovely flower; it's a nice, unusual composition, though the angle might be more dynamic I think. You might watch your histogram for overexposure in the future, though I suspect this was a hard flower to photograph! Harder still, it would be nice to have a bit more shadow detail on the leaf.
