Cool set and good eye for seeing it! - I might crop out an inch or so from the top of shot 1. Your crop through the 3 whitish circular electrical components is a distraction for me.
I might try to convert this to BW/Monochrome actually - I'd be willing to bet it would be equally strong if not stronger. It's already quite vintage looking and the BW would help to really push it in that direction.... and I do not know who originated the phrase 'colour is the enemy of form'...but for me this shot is much more about the lines and form than the reddish colour in the brick.
Hope that may help - just my
