I’m a sucker for environmental effects so I think it looks cool, if perhaps a little unrealistic. I mean, it’s the medical wing, and the neurosurgery / cryo unit probably has reason to have extraneous blasts of cold vapour everywhere, right? :) I’m assuming other areas on the station will differ, even the maintenance tunnel at the end of the video only has a hanging smokey effect without the jets of steam.
I would like to see some other areas of the station though, I presume they’re much closer to showing these off by this stage in the project. Showing the medical wing again with nothing else was the only disappointing thing about the video, but still it’s looking great if they can see this to completion.
