Just realized you asked for c&c. These are awesome as they are. I feel like, since these are really environmental shots, that they're cropped too tightly. I'm not sure what I would have done about the lighting on 1 and 3. Her head going up is the right thing, esp on No. 3. Maybe No 1 I would have had her face looking straight forward and (thus lit by natural light). Maybe I would have added a flash to No. 1, up high and behind her to light her face and backside, but the light would have be really controlled to keep from messing up this really gorgeous ambient natural light you have going there. Aside from the cropping, 1 and 3 are the only ones I would probably want to make any changes on. The others are, for me, impeccable. great job!
