Hi Tracey and welcome. It's unusual to post so many at once for critique, and the files aren't really very large, what sort of things do you want to know?
It's difficult to be certain from such small images, but you seem to have problems focussing on the subject, the technique is generally to focus on the nearest eye. Humans look straight at the eyes when we're shown a face, and it jars somewhat when they're not sharp.
