1) Most excellent. Arm shadow is a little distracting but there's probably no help for it. (It should be noted that I have an irrational hatred for shadows, probably because I end up with so many in my own pics, and am probably oversensitive to them.) Might benefit from a bit more contrast - the brightness level gives a good mood to the scene, but it's a little muddy on my screen. Pose, expression are great. Perspective is a little low, maybe, but quite acceptable. Nice framing.
2) Not sure I like this solid-color outfit on this model with this background and in this lighting. Her head feels like it's floating in space a little bit. (Easy solution: open up the outfit. *evil grin*) Lighting does nice things to her hair but her face is a little blown out. Framing is good, pose works well with background and fence.
Keep up the good work!
