I was thinking that you might put in the following:
(1) You might put in some more illuminated control panels and some illuminated screens (like those from Mega Pack 3 pictured below) and put them on the square pillars where the green plasma barrels are located, or on the wall behind the alien bodies. It can look like health monitors that monitor the health of the alien bodies.
(2) You might also put in some illuminated keyboards at both curved computer monitors. I saw one, but I wonder if the other should have one also.
(3) You might also put in a small blinking red light on the wall (similar to the ones on the original Star Trek TV show for the red alerts) or small lights on the wall as emergency battery back up lights.
(4) You could also put a small thin red light strip on the side walls behind the alien bodies, or next to or behind the rounded blue and red barrels that are in the metal cages. I thought it might add some mysterious ambiance to the place also.
I wish you all the best...
