What I see immediately, with your top image (file_404774.jpg) is that around her left arm-pit, that whole area looks 'plastic'. That stands out to me right away. I don't mind her skin tone. We all tan differently.

And there was parts to her that look totally realistic: her legs. Especially her feet. Fantastic job there. The upper part of her body just seems to reflect too much, where skin more often absorbs it. Or at least the reflection (if oily) should be dulled a bit to make it look more like skin and less like a manican's skin.

Really great though. Good work. Can't wait until it's 'perfected'. Keep up the good work!
