#1 - like it, agree with some of the guys that the lips highlights are pulling too much.
#2 - again the lips (to a lesser extent), the light looks a bit strange, not as a power but more like direction (maybe her right side could be a bit darker, maybe spill from hair light?), the crop on the elbow is a bit distracting.
#3 - similar to #2, would prefer to see less light on her back, the pose is really nice.
I also find the overall lighting a bit harsh bit this is strictly my preference - if this is your goal/style, go for it. Just my 0.02.
Overall, a very good effort. Thanks for posting.
