In this day and age where everyone cries Photoshop, you still have to be careful. I do a lot at capture at times, always have, but if it looks like it was Photoshopped, it might as well be. Color and treatment of this sort either floats your boat or it doesn't. It doesn't float my boat personally, I'd rather see something a bit more refined and pleasing, blue or not.
Since we are commenting on things that might not work, I'd have to mention that the eyes and the particular subject bother me. Too much white showing and I'm not interested in what she might be looking at. I do like the lines of the second one and it almost works.
Edit: as a one off, I'm liking the second one on my third look at it.
