First, a little less box-mapping. I recommend adding/expanding some rooms that add shape. For example, you could expand the throne room up a few tiles, or add some tiles to the armoury room so it could hold a little forge on an outer wall! What you did in the new version of the basement was great and got rid of the box-mapping.
Another point is the carpeting into the entrance of some rooms. I used to do it a lot too, until a few people pointed out carpets are rarely like that. The entrance to the library, for example, try getting rid of that one tile of carpet and see how it looks.
My final point is smaller and are way more subjective: get rid of the autoshadow on interior maps. Subject to opinion; some people like interior autoshadowing.
Keep it up; your maps have a good feel to them!
Now, I have a map of my own to post that I'd like some feedback on. Why I continue to torture myself by putting large mountain areas in my game is beyond me. But here it is, another mountain! It's a small mining town in the desert mountains; their operations have created unstable caverns underground, resulting in chasms and quakes.
