Tell me what I could of done better or changed

In the first portrait, the model is OOF. Best shot of the bunch is #2.

I agree. Actually I thought number 1 looks like a soft filter was used. Which is ok IMO. I agree about number 2 but number 4 I think also is good.

For the first picture, her body looks really cut up and out of focus.
The second picture is decent but rather uninteresting.
The third picture fills the frame too much and the lighting is off.
the last photo looks like her arms are cut off.

However, I think overall, the subject is beautiful and I think it's great that you are trying out different compositions to see what works and what doesn't. Hopefully, on your next shoot, the photos will turn out even better!
