Nicely photographed, with sharp detail. I'd like to see a contrasting shape introduced to break up the pattern of repetition so that viewers would stay in the picture to admire this fine detail shot.
Lighting seems a bit too head-on to really emphasise the texture. Some feeling of rough/smooth with those edges and surfaces survives, however. Perfectly well in focus, but seems to lack that edge of detail - processing? camera? don't know...
