The monitors need a sheen to them, a little gloss or reflection to give them roundness. Flat-shaded, they stand out.
And, not a pixel crit but more structural, I would expect the space above the three monitors to be protruding, like an old school arcade cabinet. I would bring it out and down, obeying the perspective, and add a little shadowing underneath.
It actually looks a lot like something I've pixelled before, only better. I like blinky things.
