Here are my ratings (when possible) and comments for each:

1) 6/10 (nothing speculator to write home about)
2) 10/10 (only the model that looks human and isn't frowning)
3) 8/10 (excellent movie pose, decent clothing and the make-up suits the scene)
4) ... Why?
5) 0/10 (hideous)
6) 0/10 (not sure if the model is trying to imitate a zombie, drug user after smoking/drinking or hopeful rock star that never made the limelight).
7) 6/10 (clothes are good, model isn't)
8) 6/10 (excellent Halloween costume to look like a mannequin, otherwise 2/10).
9) 5/10 (modern version of elegant black dresses, very futuristic)
10) 8/10 (nice outfit, model is horrible as it looks too masculine)
11) LEGS! 10/10
12) Polished tool from the Dark Ages?
13) Looks like porcupine quills, fashionable if the idea is to ward off people.
14) 8/10 (best piece of clothing so far)
15)
16) Looks like part of a toilet seat, I guess it's for a plumber?
17) 8/10 but lose the belt on the head.
18) Grey.....
