This is not only unpuigged but almost tangled. It would have helped more to show the actual plug. Nevertheless, a good shot. Bumping up.
Maybe I am just burning out on B &W, but there isn't enough tonal contrast for me in this to use B &W. I like the overall shot, though, and think your composition and focus was great.
I like the simplicity of this entry. Composition is reasonably good but feels a touch top-heavy, even with the microphone sitting in the lower half. Black and white works well to emphasise shapes and textures.
