Love the HDR, perfect setting for it. Where is this hospital? I've spent a long time looking at picture 3, didn't know what I was supposed to be looking at to begin with, the rusty window frame and the metal bars are very sharp and focussed, which makes me wonder what the dark shape in the middle is. But when I look at the x-ray for a while, I think it makes an intriguing sight, but the other parts of the composition are distracting, would be good if they were softer.
