#1 isn't very interesting. It's just a photo of a pretty girl, too tight for a headshot but otherwise pretty much just "this is what she looks like"
#2 has some sizzle. Not sure I'm loving the blown highlights, but I *think* they work ok here. Might be a little overdone.
#3 looks weird. Were there strobes involved, or did you just botch the lighting up in post? It looks like excess fill flash, so the light "feels" all wrong. pretty girl, though.
#4 just looks like mis-processed film to me. The weird patch of light on the left side is trying to set a mood, but it's failing and looking like some energy creature from star trek that feeds on sorrow.
#5 is visually chaotic, too busy for my taste, and I quite dislike the white veiled appearance over the whole thing
#6 is potentially very good. It's not quite coming together for me, possibly the framing is too radically "wrong" for my taste? Graphically it's quite strong.
#7 is a fun concept, but ultimately it reads as "douchebag hipsters ****ing around. The photographer probably wore a porkpie hat and black frames with no glass in them for this"
