It has some nice detail to it and I also like the background and the colors you used, but the proportion of her breasts are poor. The right one is clearly larger than the left one. Also, her collarbone on the left side should be showing to some degree, while the right side looks too close to her neck. Perhaps you should work a little more on your female anatomy. It's definitely got potential and it's well done for the most part. I do enjoy your artwork, so keep it up!
