Lovely stuff. Beautiful models and lovely poses. Lots to like here.
Now, for the small stuff I'd suggest changing...
1. The pose, outfit, and composition are all top-notch in my book with three small exceptions. First, I don't like the little black pocket on her top (and I mentioned that in a previous thread). It's a distraction. But that's a very small, niggling thing and may just be my bias. Second, that overhang of her top...use a clip or some tape on her right side and make it form fitting. Loose tops have their place but this one in this instance with this pose is distracting. Third thing...her left arm covers up the small of her back (which adds a couple of pounds to her). If she just extended the arm back a little bit more (so we could see the small of her back)...between her form/size and the pose (the twist at the waist--very effective), she'd look amazing. It's a fine photo, lovely pose and like the setting. But those 3 things jump out at me.
2. Very sultry and "come hither"...outstanding in my book. One thing I'd want to change--the weed on the right of the picture is in focus, intrudes on her and it's a distraction. Given the narrow DoF, there's no problem with an out-of-focus weed or stalk but this one is sharp and clear. I wish it wasn't there, that you'd knocked it down or pulled it out. But that's a really good pose and shot.
3. I love the concept...the eye of hair over one eye, very narrow DoF, focus on the eyelashes (which are long and sultry). But I think that in this one specific instance, a slightly bigger DoF would have been better. That sun on her hair on the left (her right side) is beautiful and b/c it's bright and light it draws our eye. And it's only partially in focus. IF...there hadn't been that sun. Or IF....there had been a little wider DoF. Or IF...you cropped a bit on the left side and then darkened/blurred out the bright strands of hair, I think it would be a more effective result. And I feel funny saying that b/c, quite frankly, you have done a lot of stuff with that pose that I think is very effective for glamour head shots. Frankly, if the backlighting/sun was a little more uniform around her, that would be pretty. But as it is, the one side combined with the narrow DoF is just a little bit distracting.
4. Facial expression seems just a little stiff. Otherwise, that's a really fine photo. Using the tree trunks to frame her--nice compositional element. One strap down--subtle yet sexy.
5. Totally lovely. I think the first time I saw this shot there was a distraction in the background (tree trunk?) and you've eliminated it--well done. It's all good.
Five lovely shots, very sexy, beautiful and a couple of them...seductive as h3ll. Well done. Thanks for sharing.
