Two things in this video that bug me and I think should be changed. Seen it before in the capital ships too.
1) if they are holding position, then the main engines should be off, without any visible thrust coming out. Maybe this particular station was en route or station keeping, but some other ships I've seen are in a fixed orbit, and yet the engines are going full blast. They should be dark, or at least at a minimal activation, with a dull glow or something. And actually, this applies to ships as well...ever notice how inside the station looking at your own ship or others, they can be parked, and yet the engine is on full. Need a bit more dynamic change there.
2) I haven't done it is a while, but when Anacondas first came on the scene as NPCs, it was cool to get right behind one in its engine wash and get that sound and sense of power and vibration. Now, imagine doing the same thing in one of these engines...shouldn't you at least get some heat or shield damage? Something? Parking inside a station or capital ship's engine bell while it's on should be something you do only once, for a good reason.
Sorry about the rant. Love the idea of seeing growth of a station, rather than it just popping into existence. Add some construction tugs whizzing around, and you've got me convinced it's actually happening.
