First off Rex, you have a beautiful daughter that you should be proud of. My favorite image is #3 but it has a little red cast to it that could easily be fixed in post processing. I also like the last one.
I like the way the lines from the hammock are used compositionally in the first shot, and the DOF works well here. The second shot is less effective IMHO because the rope blocks part of her face.
The third one would work well has a horizontal 8x10, very nice.
These all have color casts to my eye. I agree with Gordon that the third shot has a slight red cast but I find the skin tones there more pleasing than the other three. You mention these were straight from camera, with a bit of tweaking in levels/curves or the color balance tool it should be possible to get a more neutral color balance.
