Excellent composition. i think the placement of the needle/cartridge is perfect as well as the knobs and controls of the set. I actually feel the focal point is good here. It is on the head of the needle nad it looks sharp enough to work. I agree about the bright knobs in the upper right, but they do not bother me to the point that I would do anything about them. Perhaps burning them mdarker might be good.
The b&w is effective in bringing the nostalgia to this subject and the old school feel.
Nice work
