The crop is too tight on the left side and she seems like she's getting pushed out of the picture.
Crop is a bit tight still, but better composition. The line of the ground seems very centered and I would've liked to see a slightly higher or lower angle.
Good composition and juxtaposition.
The bright empty space on the left behind the girl's head is a bit distracting. The skin processing really kills this one for me.
Again, the crop is odd and there are parts of limbs floating around the edges.
The focus is very centered. I would've liked to see that curved branch in the background used somehow in the composition.
Overall, the post processing seems rushed and sloppy. Maybe because I don't know their story, but the use of selective coloring doesn't really make sense to me as someone viewing it. It might have more significance to them perhaps. Their skin is completely desaturated in one shot and then over-saturated in another and I don't really get what you were going for. Also, most of the post processing seems very extreme and overpowers the image. You seemed to just mask out a circle area of what you wanted and then blurred it or desaturated it.
