The first image just looks way overexposed to me ( and lacks pure blacks, as you'll see if you check the histogram , or simply do a Auto Level ). The background has some wrinkles that is visible. I like the models expression on this one though.
The same goes for the second image ( something strange beside her left hip ). The lighting does nothing for me on this one. For fine art you would usually have darker shadows and let the contrasts do the image. What did you change in Photoshop for this one?
