I have some specific critiques on these that may be helpful when doing this again in the future.
#1, Too much area on the top. I would crop it down so that it comes to about an inch above her head. Good background light, but her face is too dark. You can use fill flash or a reflector to throw some soft light back in the face.
#2, the setting is beautiful, but if you want a good outdoor portrait, it would help to zoom in on the subject more. Again, more light is needed on the subject's face.
#3, the sunglasses don't work in this one IMO. If you are focusing this close on the subject's face, we want to see the eyes. Besides that, there are shadows on the face that distract the viewer again.
#4, Much better. You have some good ambient light going on in this one. Its soft and gives some shape and contour to her face.
#5, Nice pose, but I would definitely get in closer here, so that you focus on the upper body and particularly the face. It helps a lot when the subject looks at the camera in this type of pose as well, so that the viewer gets a connection. Lighting is not bad again.
#6, Kinda cool, but need to get close again.
#7, NICE focus on the face, but too much area on the top again. Also, dont cut off the elbows. Good lighting, and background elements were kept to a minimum. Good job.
#8, Again, nice focus and good lighting. Too much area on the top and don't cut off the fingers on the bottom.
#9, Cute pose. Again, too much area on top, and there are a few distracting background elements in the yard over the fence.
#10, Nice ambient light. Maybe needs a bit more contrast and color. The cinder block wall and garage door don't do anything good for the background.
A couple more general things. 1) You may want to do some post processing and work on smoothing out the lines a bit on her forehead, especially in the closeup shots. Nothing drastic, but just enough so that we are not focusing on the lines, but on her eyes. Its all about the eyes in portraits. 2) Be sure to number your pics, so we can reference them easily.
Lovely model. Would like to see another shoot of her if you can.
