After fixing the 2 things that were said here that really bother me when I look at this (the bikini and the neck area), try duplicating the layer and play around with the blending mode. Try "overlay" and try playing around with the hue/saturation on one of the layers (ctrl+u). That can bring out the "finishing touch" out of the image quite nicely. :) Excellent work on the stiches, BTW. I really like it! :)
