I really like #3 with the camo and such but your camera is eye-level with the model. Some attitude would have been nice. Personally, if I'm going to be higher than the model, I want to go ALOT higher...but in general I prefer shots where the camera is chest height or lower. For a shot with this outfit I would have gone a lot lower to infuse more Dominance in her appearance. Also, a different expression would be good. Smiley isn't always needed as evidenced by shot #4.
Speaking of shot #4, I think the far eye is getting blurry too soon. If you wanted that then your shot would probably work better with a tighter composition and even more DOF (or less depending on your terminology, I think mine is backwards. Have a 1inch DOF instead of a 4 foot DOF. Great, now I'm confusing everyone who's reading this.)
Anyway, nice stuff.
Could it be any more awkward to post an image?
