I missed the last few updates - sorry!

It looks greatly improved since I last caught sight of it - great work.

The lights seem to bleed into the walls a bit too much. I know you have some kind of bevel on the walls, but I think it might look better if the bright white and yellowness of the light was confined strictly within the open space of the cave, and not allowed to leak out through the walls like that.

Again - try it and see
