I think you have done something right since it does look like part from clean space station :)
Not sure is it table or some sort of control device below holo, but what if you could flip that so viewer can see all buttons and what ever there might be. Right now it's something middle of space and not clear what is that purpose. Also at least for me it was difficult to realise holo is NOT further away from the table, but actually it's closer camera. Maybe I'm wrong, but image needs some sort of reason I think?
Have you added noise effect or is it render issue? Anyway to me image looks good, but that table put me wonder what's going on! :)
