GK Level Tips?
 

Here's a GK house level I made, and I would like some tips on it. The overall aim was to be the entrance of a haunted house. (The owners of this house have been dead for hundreds of years, and there house is infected with their ghostly spirits.) I've also included the .nw file if anybody sees any things such as tiling and lighting that need to be fixed and they want to fool around with it.

Help is appreciated! :D

If a house has been in disuse, aside from the occasional treasure seeker and explorer over the years, there should be more imperfections on the floor - especially given GK's medieval tones which would already show some crap architecture.

And symmetrical is dumb. It works for dungeons and castles, but there's no reason a house should be both abstract in shape and symmetric.
