Let me start by saying that this is some nice work, you've got an absolutely stunning model, and thanks for sharing these with us. Good portraits.
Now, let me offer C&C:
As an overview, let me offer two thoughts:
--she's wearing a dress with a strong visual pattern (horizontal lines, dark and white). So look to pose her with backgrounds that work with that. I'd either be looking for a background that doesn't compete with it (use narrow DoF to create a blur, or a white/uniform backdrop). Or I'd be looking to integrate her into the surroundings (with a background that has strong horizontal or vertical lines). Otherwise, the background ends up looking busy.
--she's tall (or at least looks it), slim, with heels. So....use poses that take advantage of that. Get her standing. Look for triangles (more on that later). Get lower in your shooting angle. Have her use her hands and feet to help create visual illusions that accentuate her height (more on that later).
Photo specific comments:
1. Background is cluttered (the prints on the wall specifically). You've cut off her right foot (a no-no PLUS it cuts off the line she creates). Not wild about her right hand. And I'd make her left elbow straight (so we get this terrific diagonal line--very active and dynamic in photos) running from her arm to her leg. That said, that's a terrific pose for most women and in particular this model...kickass triangle with the legs.
2. Love the pose, don't like how the table bisects it. Also, not wild about her left arm...you need to play with that a bit. Otherwise, lovely pose.
3. Effective composition (B&W with the red). Not sure about the crop/framing decision...I think you want to step back and get more of her form...she looks very short and not very flowing in the photo. I'm not a big fan of symmetry so I'd actually make the hands more uneven rather than matching in pose. The biggest thing for me is that her hair just blends in to the black background so you'd benefit from anything that would create some separation from the background. Some backlighting or a headlight would be the way to go here.
4. Lovely pose but the dress (over the knee) makes it less effective in this case. Also, the dominant line is that division between the phone booth and the wall and it feels like it's not absolutely vertical (may just be an optical illusion).
5. Great pose but the graffiti in the background detracts from the photo. If she was going grunge or edgy in her clothing or she had tats, then it would work for me.
Great work.
