Very nice series. They are all well lit, but some just have "awkward" or "forced" poses. My only real gripe is the background is SO distracting on the second one.
First one looks like a manikin the rest are ok but still to posy I do like the last one the best and # 5 is nice. Natural smile/pose nice lighting and back ground.
They are all very good from a technical standpoint, but I can't help but think of Zoolander-she has nearly the same expression in all of them. To me, that indicates that you maybe needed to build a little more of a connection with her, have a conversation, get her laughing.
Taking a second look, she also has her head at exactly the same 3/4 angle to her body in all of them, so work a bit on doing some over the shoulder, straight on, and working with the angle of her face more.
Excellent shots; the best series i have seen from you; yes, in some photos her face has same expression; she looks gorgeous in second and fourth. Her smile in the last is fantastic
PS: how difficult things turn when you don't number them
Those are good. They're a little posed though. I think they would be a little more effective if you caught her off guard. I still really like them though.
