Hey--nice job! I have no idea why you thought you could possibly be "out of line"--you have used the Guild exactly as this forum is intended!

I think you have done some nice things here: this is a clear map, very moody (mainly because of the black rock fill). The way I see this map is that it is really a schematic of these dungeons/sewers with a bit of fancy touches added in coloring and texture. Clear and straightforward, so I can think of no major suggestions.

If you wanted to tweak & play just for the heck of it, I say 1) adjust your grid so it's not so sharp; for example, put the grid layer in color burn or multiply blending mode & turn down the opacity a bit. 2) You could also add some glow to your torches, and darken the rest a bit more. 3) I also think A5's items clash when compared to other placed items (as in c4) because they are symbolic vs. literal top-down views (or visa versa).

Nice first post!!
