I think photo 1 has slightly awkward framing, and would have looked better with the camera swung a bit to the right, so that there would be a bit of her dark sweater in the lower right hand corner, to help anchor that. I think it would have looked much better from a perspective point of view to have used a longer focal length and moved the camera to at least double the distance, since the close-range shot is making her nose look exaggeratedly large. The V-neckline of the sweater is pushing the viewer's eyes down,and right out of the frame. Framing this a bit more loosely, with some sweater at the bottom, might have helped the shot considerably. Good focus though, and nice bright eyes. SImple foliage backdrop, so points for those things.
To me, the second photo, while it might be a bit overexposed, is by FAR,and I mean by far, the absolute best shot. You have captured her at the peak of her jump, and yet there is a little bit of foot motion blur, the repeating shadows look good, and the composition is pretty solid. Sure, the highlights are a bit blown, but maybe it could be post-processed a bit more to massage the photo into a slightly better technical image, but overall, I LIKE the shot. It's fun! It has dynamic action. Technically a 7, emotionally a 9.
The third shot...my pet peeve #1...horizontal framing on a vertical subject that is far,far taller than it is wide. Her angle to the camera is also poor. Had you turned the camera to portrait orientation and brought her right shoulder around about 30 to 45 degrees, she'd have two shoulders, and a bustline,and the shot would be solid, and the portrait orientation of the camera would have eliminated that big, black area of dead space in the back right hand side of the frame. The processing looks okay to me--soft, slightly ethereal and diffused. Her wardrobe and necklace harmonize with her hair, makeup, and everything, but we literally can't "see" much necklace or wardrobe, just one shoulder's worth of sweater. This extremely side-angled positioning of the body is not very flattering,and leads to just a head, floating on top of a single shoulder.
