I think there is too much space on the right side of the picture. I know that there's the whole rule of thirds thing, but that space is just too bland. The image would have worked better if we could have seen the whole hand and phone. The colors are a little rough, but it might have made for an interesting contrasty black and white. The subject made good eye contact, though, so I think the idea has potential.

I like this - maybe a tad dark - but I like it.

Nice shot. Not sure whether she was caught off guard or not for this. I love the colouring and contrast in the face.

I think the idea in this shot works, however there are a few things that (I feel) let it down. Firstly, she doesn't look sharp, possibly a slow exposure, there seems to be a slight movement blur. Secondly, the dark area seems too dark, you've lost a lot of detail & it's become a black hole in the picture. Thirdly (and now I'm getting a bit picky) the dirt on the wall on the far left and on the phone distract my eye.
