Bahaha. This map is actually really nice. The shading is great, and the layout looks unique and fun. The only problem I see with it though is that barretters can spray from one side to the other down on the bottom route, since the terrain is flat; give it some varying elevation.
Not to be an ass, but the lighting effects (those beams of transparent blank.bmps or whatever) are crap. They just don't fit well with the map at all. Use
this instead.
Keep mapping, please. I'd like to see more DM maps from you (or whatever else besides climb maps, there's just too many of them).
