Oh come on Scoody! You know to number your photos by now!
Let me have a go at it...
I think over all they are not bad. As evidenced by her mom buying almost all of the shots, you obviously did a good job. The following are things that I think you can look at to get even better shots next time and maybe even sell ALL of them =)
1 2 and 3... Dappled sunlight is almost always a bad thing in portraits. The light and dark draws the eyes all across the image.
1. It seems a little underexposed. There is no detail in her hair that could probably be fixed with sharpening? I saw someone fix this the other day though I forget how. The bright spot on her right breast is a bit distracting. I can't tell if it is a dapple of sunlight or her tan line from wearing a swim suit. Either way try to even the skin tone there. I think this would be a lot better with the two lines not stabbing at her face. The light and dark at her face with those lines is terribly distracting. It would have been nice to have her looking directly at you with a little more catchlight in her eyes.This is a quick edit I did.
2. Smile looks forced. Same in 3. Having her facing more towards you would have elongated her body and made her look more sophisticated. Make sure her hands are doing something. They just looks kinda "laying there" to me.
3. Don't be afraid to "fluff the dress" (Big Mike can give instruction on how to do this) The knee peeping out looks out of place. It should have been covered or the whole leg should have been exposed. The floating right hand is the same. Though it should have been showing (side to you not the flat back of the hand) with the dress covering her knee.
Again, not bad overall, just some thing to pay more attention to.
