Better already. I'd still go for a control room, the control platform now can only be reached trough the spore room. If these specimens were dangerous or fragile or anything like that, it wouldn't be good to have people running trough the room everytime they want to monitor them.
I'd also go for the tubes around the spores. They are alien specimens and maybe they're not very adaptable to our environments and therefore need specific conditions in order to stay alive. Humidity controls, air pressure, such things could all have effect and instruments that monitor and maintain these factors are off course visible to some extend (or integrated into the walls or such). And off course a lot of screens and control panels would then be necessary.
All this to establish the feeling that you're in a real lab. Those newest screenshots look better already but still don't have it. The lab look. Some other textures might work better, as well as some more contrasting lighting. Dark ceiling, greenish glowing tubes that contain spores... walkways that are lit with floorlights, giving such a futuristic, gloomy feeling... Oh, the inspiration!
