Nice mood!

First thing I notice is the red lamp. I think you ought to do this without colors (ie bw).

I would also try to heal the rope/thread hanging from the left.

The brightest areas looks slightly overexposed .

the red of the lamp(?) is mutch to strong... very nice mood though... agree with moser about trying to clone out the thread... still wel done

Great contrast. I was going to say the same things as moserArtist. Try it in black and white and decrease the contrast ever so slightly, while bringing up the brightness. (Curves editor would be a good one in this case.) There's a lot of light that should be reflecting off of the wall that's missing.

Again nice mood and overall composition.

Cheers,

Nice work. Maybe a tighter, narrow vertical crop?

This looks like it would make a good sci fi PAINTING!! =D

Yeah, great contrast.

I agree with Mr Patrick!!
That red thing distracts me...

I like the combination of shapes and shadows.
Very nice composition and mood!
I would also heal the small bright spots and the red one.

I guess I'll go against the opinion here but I'd keep the red but I would get rid of the blue tones. I'd also clone out the wire in the front. I like the high contrast.
