I loooove 5,6 and 7.
1,2,3 and 4 look kind of like screenshots from a TV interview - that's not a bad thing and actually, the more I look at them the more I like them for that reason.
My biggest problem is with 8, 9, 10 and 11.
8: The feet are cropped and I think there is a little too much headroom. I think simply pitching the camera down would have made that a great shot. Particularly as her face is highlighted by the dark background.
9: I personally would have cropped in a bit tighter and moved her over to the left, as if about to lean back onto the edge of the frame. She's almost floating in the middle at the moment and there's a big stick just behind her head.
10: Again, I would have cropped tighter (less headroom) and moved her left. It would have balanced out the brightness of right hand side of the frame and again, there would have been just enough dark to highlight her face. As it is, I think the light left and dark right are too "equal" and are conflicting with each other.
11: Purely a costume design error. I think her pose is fine, but that bend in the tartan of her dress makes her look pregnant. Another tighter crop too - I don't think the ivy adds anything and might actually be fighting for attention from the model. The plainer background would have made the dress (without the pregnant!) really pop.
I love the last 4. I have a penchant for a landscape portrait (that should get a few people around here's heckles up

) and the poses in the vertical ones are just great.
Nice work overall
