LOL The layout reminds me of a HeroQuest map - including the little green circles around the monster icons. Good work!
Nice style. :) I agree with Malcadon, makes me think of HQ and AHQ maps. :) Or Nethack even! :) Would a gold coin or chest not be more universal or graphical when representing treasure (I mean, I'm thinking about your international market here :) )
@malcadon, I was certainly inspired by by those sources.@BB, Treasure containers might indeed be a good idea. To my U.S. mind money/treasure leaps tot he mind instantly with a $.
