Wow! Awesome photo. From all the photo's from this photoshoot, I think this is the best one of her (... I just went through all 39 pages in your gallery to make sure that I wouldn't miss one). I love the colors in this. The saturated yellows and greens in the background. The soft brown tints from the leaves on the ground that match well with her hair and skin. And then there's that big contrast from her boots and legs. But the most important part is that the subject/model still stands out from the rest. And you've made good use of the rule of thirds. The model is just stunning. Absolutely beautiful. Great pose. And I love her expression. These kind of pictures just get to me, it's like it's telling a story. There are just two small things that I would have done different. I think it would look better if the bench would line up with the - frame, instead of having that slight angle. The other thing is that I would get rid of the blues, in the background and on her shoe. But maybe those are just my personal preferences. (I just tried it in photoshop, and I think it does look better.)
So ... I hope that you appreciate my (long) comment/critique. I always learn a lot from looking at pictures like this.
