Second, horizon is crooked. I would push the color more too. Did you stitch a series of shots for this?
Third looks the best, but I don't like the distracting dark spots above her head. they do help define the perspective, but they distract from the subject. I would run the dodge tool on them just to lighten them up a bit.
1. Nice colors, but looks underexposed. Also, not terribly interesting. Hard to tell what your subject is.
2. Not too interesting, focus seems off, and the composition needs work.
3. I'm not a fan of the vignette or the sepia. Also its over-exposed and the highlights are blown out. Also you must've done some editing in her hair because I see gray patches that aren't very appealing.
