Way to much retouching. Face is ok, but the body is too obvious. You lost all the detail in her skin. Just lower the smooth layer's opacity (I hope you worked in layers) and it will be better. The background could use some noise reduction too. With model super smooth and background grainy, it looks even more retouched.
Retouching shouldn't be noticed that easy! Though, you did a good job on fixing the lighting. Try adding a few highlights like I do in my tutorial. Try a light shadow set to multiply over her breasts (barely noticable) and then a highlight directly on the breasts. They will come alive! :O

I guess this was not your own photo? Well then, I won't comment on that. ;P
