This shot begs for the what I like/don't like treatment so here goes.
What I like: This shot has a very earthy feel to it because of the subdued green color scheme. The lighting is very nice. You have all the important parts lit in a very interesting way which helps to give depth to the shot and draw the focus to the intent of the shot. The background though cluttered a little adds to the earthy feeling of the shot without being really distracting. You have a shot that tells a story and that is not always easy to do!
What I don't like: Your models finger is not the most attractive for the shot. A little hand lotion would help to smooth out the cracks in the finger. I would really like to see just a touch more of the leaf in focus but that is kind of a nit picky thing. I personally would probably have lightened it up just a touch also.
All in all a very nice shot. I'm surprised that it finished at only a 5.2.
I don't get the connection to the title and I've seen a lot of this. Might I suggest the model puts some hand cream on to soften the skin tones up a bit and not look so aged. It also would have taken the high contrast off of the finger. The photo itself has nice choice in DoF and is a fairly interesting photo because the gold appears to be graduated from the tip of the finger to the leaf and so on. Great colors and clarity. Well done and good luck in this challenge. <7>
