Nice map - I enjoyed the lighting and the detail items.
The 4 SE-ernish stairs have what look like raised floors above them or something? I'm guessing they are areas for lookouts? If not I'm not sure if those are just rooms you can't get to or something. For example the Green room: Are those 2 areas looking down into the Green area or are they on the level below the green area?
I'm not sure how best to solve this but maybe creating lighter or darker shadows on those rooms might help to indicate them being higher or lower? If that doesn't work you might want to look at how some others have handled this in their maps.
Other than that I think this is a good looking map and thank you for sharing with us.
