Okay, let's go
#1 - I love. The pose looks relaxed, the shadows aren't TOO harsh.
#2 - Lighting is far too harsh, don't really understand why there's a receptionist under a spotlight against a brick wall - it doesn't really suit.
#3 - Again, lighting quite harsh. For this pose I'd recommend a landscape orientation - I want to see her arms and legs. Eye contact is awesome though.
#4 - First thing that hits me is that it's wonky and the shadows are super harsh. Lack of hands or face is unsettling, and I think the head tilted backwards just to induce a flicker of an eye would work wonders.
#5 - Not in sharp focus - kills this one, sorry!
#6 - Her placement in the frame is peculiar. Why have her so insignificant at the bottom of the frame and then a massive harsh shadow against the wall?
#7 - Quite like this, more of the book and her ears and the top of her head should be in frame. Too tight framing.
#8 - Shadows are too harsh and her finger is out of focus which is distracting.
#9 - Quite like this one but the shadow on her chest from her knees is distracting and it's a little underexposed. Try moving the light so it shines on her face avoiding any cast shadows on her torso.
Over all, the white balance on pretty much all of them is off. Set your camera to 'tungsten' white balance and they should all turn out a lot less orange
Hope that's helped!
