#1 - very static composition. Passport-ish angle. Arms straight by side, no triangles, no lines, nothing. No offense, but I wouldn't use that as a vacation snapshot in a family albumn.
#2 - Holy armpits, batman! Rule #1 - armpits almost nnnnnever look good, even on beautiful women (not saying she is, just speaking in general). In this one, it's almost like she's showcasing them. The angle and pose is contorting her all up too. Smile looks contrived.
#3 - Very contrived pose and smile. Exposure seems a little off. The angle is straight on and her body is flat to the camera, posing 101
#4 - This one is the best of the group IMHO, but looks quite "flashy" I would have used a more triangular base with her arms in the pose. But overall this is a decent shot. I also would have angled her out of the photo a little more, in other words turn her a tad more toward the camera, that would also have thrown her body out of focus juuust a tad. Hot spot on shoulder. Also, on my high-end crt, I can see whta appears to be some editing articact to the left of her mouth from the camera's perspective, it almost looks like light orange.
Thanks for sharing
