This looks like an interesting map.
I do have two suggestions, however.
One suggestion I would have after looking at this map is to not use the broken floor tile as the whole floor. I would only place it in a few places. Looks kinda messy other wise, in my opinion.
The other suggestion I have is that pillar in the top right look kinda weird standing in the middle of the room, as it is designed to be placed against a wall. It looks somewhat cutoff otherwise. I would suggest either moving up two spaces against the wall, or replacing it with another pillar.
Hope this helps!
