Yes I would say that it looks better this way. Cleaner and the area of interest is more defined. Also like the new border. Nicely done. One little point about the stairs though. You have to watch out for the shadows. For example, the stairs north of room 12 are obviously going up....but once you get to the landing, the shadows on the second run of stairs should be reversed from those of the lower run. This would give a clearer indication of where the stairs are going. But don't worry overly much, this is a good map and stairs are not always the easiest thing to wrap your head around at times.

I think much rep worthy
