Here are a few quick notes:
#1 has lots of color cast problems. It looks like you were trying to get some of these color effects, but they didn't work very well and you have some purple fringing around the hair. The cropping/composition has problems especially with the arm on the left side being cropped below the joint. Usually better to crop above the joint. #4 is the best composition but both it and #3 seems to be a bit soft (especially the eyes).
