Well, it's a vast improvement over your previous iteration. I enjoy the clean spytech theme a lot more for this point.
As for the ceiling - it looks like you're using a natural rock texture. Are you planning to make the ceiling rocky? Cause if not, it just looks like icky red marble or some form of dorky wood, neither of which match the theme really well.
You could try doing a light cream color, similar to this piece in Junction or Hydro:
Or you could use the dark brown/red that you've used for the pillars to sync up the pillars to the ceiling, similar to Converge or 2Fort:
My personal favorite is mixing these up with natural rock, but unfortunately, Badlands does that, too. And at this point, anything that differentiates the point aesthetically from Badlands is probably a good thing.
Hope that gives you some ideas!
EDIT: Oh, I don't think your ceiling is the weakest part of the scene. I think with some creativity, you could easily make it one of the strongest aspects of the scene.
