Really like the idea/concept, and do like the overall picture but he subject is too dark for me, and there's too much contrast in the chain. Also I can't quite work out what you've done as there's part of the chain at the middle/bottom in the forefront that's out of focus yet the back part and top part are sharp and I can't get my head around how/why that has happened? Also the loop of the watch is out of focus.
If I just look at the picture I really like it, if I critique it I can see flaws. Therefore I'll choose to just look at it from now on and really like it
