Your avatar is the only good new one.  I'd kill the other three.

Well...  as far as the white coat series go -I think they have their strengths.

"The color white coat on tree":  Face is lit in a completely satisfying way.  Really lovely.  But I don't think your body position vs. camera position is flattering. 
And the composition suffers accordingly.  Also exposure is off in patches.  But color is generally good. 

"Black&white white coat full body":  Good lighting overall, but I don't think your body is positioned in the most effective way.  I don't like how the perspective shortens your body.  I do like your face, your hair, the detail in the ground, the lighting, and overall tonal range.

"Blue train" is OK.  Don't love it.  Don't hate it. 

Avatar is the best.

Overall not bad.  Strong effort, but would benefit from better pose postions, attention to composition, and tighter exposure control.  I am holding your work to a higher scale because its obvious that you are not a begginer per se.
My advice:  Learn what camera angle/body position combos are most flattering and least flattering.  At your next shoot, you'll be able to adjust yourself accordingly.
