This is a unique idea and well composed image. I love the way the sharpness fades into the background. Too bad the clover is not sharp. Your lens might have been too close to it for good sharpness. Also try making the border dark green. The black doesn't fit with the rest of the soft colours.
I would have preferred just a little larger depth of field, bringing some of the fingernails into focus a little. Nice compositional balance though, and red/green is slap bang on the challenge (unlike some of the competition!)
