A little flat and dark. I think it could use a little boost of contrast. I like the placement of your subject and the crop of the picture. Nice perspective.
very nice composition. a bit soft in focus, and the low contrast accentuates that. the lower right is a bit bright and draws attention out of the image.
Beautiful flower. Focus seems a little soft, which doesn't work too well for me in a macro-type challenge. Love the composition, though, and the colors are quite good.
