Messing With Dungeon Maps

I did the map below in AutoREALM. Not really happy with the way it came out...coloring, perspective, etc all somewhat off.

My goal is to create a single map of the discovered portion of the Montporte Dungeon, with just enough detail so that the players can maintain their bearings as we move from map to map. The map below only contains the three levels that the players have down in terms of location. They have explored a lot more, but thanks to a teleport, they do not know where they are in relationship to the area displayed on the map below. They are in a whole other area of the dungeon.
It feels a little too small and plain. But it is a start...and maybe some of the Montporte players will find it helpful.
