I love the texture and the interest of the different shapes crossing over each other. It is an appealing abstract for sure -- perfect in black and white.
I really like the composition with the diagonal line, the glare doesn't bother me though I might boost the contrast a bit. This has a nice industrial feel to it, nicely done.
I'm liking the background fence if your purpose is to show the relationship. Excellent detail and contrast between the links, particularly the different metals involved. As for the white spot, you could clone in and perhaps fade slightly the detail from the area to the right of the spot.
