They're all so gorgeous! Lol, i think i added you on my flickr.
For #4, i think a little more contrast on the shoulder' dodge/burn a little in photoshop would give it slightly more dimension, as it draws the eyes in. Nonetheless its beautiful already.
I love #5 much more than the other ones. Silk is pretty in photos, but there's something honest and pure about the texture of cotton or linen that comes across the camera so well
