#1 I love that blue color...the flash seems a tad harsh, though. And maybe too much DOF? One thing (and this might just be me, lol, but I don't personally like props that are just held like that...I much prefer something like #3 where it's actually being used, and it shows more of the personality and character.
#2 That's a really interesting background. Maybe vary up that pose a bit? That shoulder being raised seems to make her look shorter. Maybe some addl reflector to brighten up the eye sockets? Her neck looks more pushed forward than #1, which is more flattering. Might be nice to have a diff expression from her on this one (most in 1,2,4 seem the same?)
#3 I think #3 is the strongest, with the attention drawn to her, and the angles with her arms, etc. Only thing I might want to see would be shallower DOF, but that's just my personal pref.
#4 I feel like her face should be brighter here, maybe a little less 'flat' lighting? I like the DOF. I might clone out that lower white painted line to be less of a distraction. And I'd probably crop in tighter...
