I like the look of the map overall, thought I think maybe throwing a subtle pattern over the borders might look nicer, or tattering the edge so it looks like it is on cloth or parchment, etc. From the perspective of aesthetics, the map looks nice, from the perspective of it being a dungeon battlemap.. hmm.. slightly underwealming. I like the ideas, I think the biggest issue for me (as a long time DM) is that the rooms themselves aren't particularly exciting to have combat it. Very simple shapes, no real environment changes (ledges, columns, cover, etc.) so each fight would probably amount to the same "fighting in the middle of the room" type scenario. So as far as actual looks, then it's great, for design some more interesting shaped/styled rooms would have made this a real triumph.
