I was looking at it, and I thought it had frozen while loading - meaning, the stock is probably too far down because it gives off the feeling that it's cut off. I think you're getting better, however.
I don't like the colors on the stock though. Sometimes it's good to copy the image you used, take it and put it on top and put it on a layer blending setting so that it gives more color back into the person. Try adding more contrast and maybe a warmer and darker color to give more depth in areas.
