The random brood screams are ment to help keep people more alert on the map and help broods to a degree since if theyre unlucky and surrounded before the can split up they wont ever have much chance. ( I can change it if needed)
As for the graphical side, I partially understand wanting a more metal sci fi feel to a map, but the re-texture was overboard and I feel a map needs more variation and all dark metals. Its more designed as research base than a floating metal space station.
Also while it looks cleaner in general it gives more impact to the lights being turned off as there's more contrast, I am open to texture pack suggestions though if you can link some. I just didn't like the way multiple maps got the exact same dark metal texture set.
