Thanks for the compliments and critique!
I kinda see what you mean about the cliffs - also not sure how to fix it. I did the maps entirely in Photoshop CS2. I have a few of the Alienskin Eye Candy plugins that come in very handy for mapping. For instance the floor is done with a gradiant grey with crumpled paper and a texture.
As for what the map was used for - it was from a old D&D game of mine. I had it printed on a 11x17 page to use as a master map - not really on a tactical scale. I also cut portions of it to put in game updates to show where they had gotten - I will post the Fire Giant sequence of updates if you are interested. I ran the campaign from 1st to 20th level, then started it back over as an epic a year or so later. So all the old updates are archived.
