Very nice eye for pattern here. The roundish shapes above sets off the angles nicely. The image seems a bit grainy, and I can't see a reason for it here. But nice work.
A lot of noise (All the little colors in the dark areas) Did you use a high ISO setting or Auto? If Auto, it might be better to set it lower in manual mode. Composition is nice. You may want to play with this picture in b&w.

I don't belive that "right angles produce the strength of the image." but thepic is'nt devoid of tem so I give you some credit.
Technical = 8
Love the reflctons and the way the brass was captured..but the pic is dark
