I'd say I pretty much agree with what CW said about most of the photos, but Ill try to throw in an original thought or two. Here's my 2 cents, but remember i've been doing this for less than 2 years, so my opinion is worth less than some others.
#1. Were you going for the blue green look? IF so fine, if not maybe try turning dow the blue or green in PS?
#2. Something... The pose, or maybe the dress, or perhaps both, just aren't flattering to the model. Also, it's a little on the dark side.
#3. Looks like a fun shot and the general idea is there, but her left arm looks awkward.
#4. Is the best of the bunch, but would be better with a tighter crop, and her expression just doesn't add to the photo,
#5. Love her expression in this one, very flirty and fun.
#6. Not crazy about htis one, her skin looks pale and the pose and crop just dont work.
Keep shooting, keep posting, and always strive to improve.
