Can you use some better images?
The images you used are horribly rendered, as in, you've(or someone has) cut them off a background, the result being dodgy images.
Secondly imo the main image used in the skin - the woman standing up - is of too low a quality, in such that it is pretty blurry. I would say the skin needed clear images to make it look good, ones that have been cut properly.
For example, something more of this quality:
Relatively small file size too, 267kb, and it's probably bigger dimensions than the one you're using now. Of course you couldn't use that image though, as her head has been chopped off
