Out of focus. I'm afraid I can't stretch my imagination to see how this fits in the nude challenge, if the nails were "nude" not painted at least there would be a tenuous link.
ugh - I hate the yellow nai polish, focus is tooo soft, feet are too dark and black and blue. Okay, now start over. This is a ggod concept. the composition is more interesting than many, the interplay of negative and ositive space is interesting. With that much black space I think maybe this would be much improved by changing to black and white, The color doesn't add, the shapes are the strong point. B+W would make the sapes more abstract.
I've photographed hundreds of women, and I can't think of ONE who liked her feet - even though they may have been exquisite dainty lithe sensuous feet. Nice to see at least ONE woman who is willing to show hers in all their splendor!
the model may be nude, but the photo is blurry, and the colour is odd (not just the toes - the feet look off-hue as well). If your camera struggles with close-ups, try using lots of light and even a magnifying glass ( an inexpensive alternative to a macro lens).
I had thought about taking a shot of my feet, too, since they're probably the least offensive naked part of my body... :) I think this could have been stronger had the feet been in focus, and there seems to be a bit of a blueish tint to them as well.
