I know this is a persanal taste thing...but.....to me the thing that distracts from the Map's over all look is that the grid is on top of everything....My personal taste has always been grid only on floors..(Exception> rugs)..

Also I hate overly detailed maps for general play...Unless it is a map I will use over and over.

I also sell on DrivethruRPG...not much luck yet there.
