Camera Work/Technical: The gaussian blur makes it a it difficult to tell where your focus is. Even beyond the GB, I can still see some crisp focus on the nails and the rings. I believe I would have opened up the aperture a bit to add some blur to the background. This would have helped isolate the subject off the background a bit better.
Lighting: Your lighting is very nice and very even. The subject is lit very nicely, and the darker background helps isolate your subject.
Composition/Content: I like your choice for a centered composition here. I think an even tighter crop would have made it even better.
My Opinion: Nice job meeting the challenge. With a little less blur on the foreground and a little more on the background, this one would have pulled an even better score.
doesnt seem to be composed properly, the hands look a little ghostly
also, could perhaps use some sharpening
and would be preferred if the background was pushed out of focus a bit more
I think you might have been just a little more careful with your background - such a simple set-up is easily defeated by the odd discoloured leaf in that foliage.
