I prefer the first. Not sure about the objects surrounding her head, a bit distracting. The ceiling is the weakest part. The floor, walls, all give this illusion of being inside a metal room or something, but the ceiling doesn't play along, and that sort of breaks the spell, if that makes sense. It looks like it could be water, paint, clouds, but I'm not really sure what it is, and the spell is broken for me. So my suggestion would be to rework that ceiling and make it seamless. I do like the lighting, her pose, and the her expression.
The second shot, well, to be very blunt and honest it has that look of Photoshop kitsch, like it's the result of following a tutorial in a Photoshop magazine. The shot itself doesn't look bad to me, and I am wondering what it would look like without all the extra processing, and converted to black and white.
