Doing a strategy android game with hand drawn maps. What maps would you like?

[Darkying]

Here it is. I'm just a polishing an android strategy game loosely based on Liquid Wars, but I'm out of ideas for maps. All maps are hand-drawn in paint (black over white), like this , or this, but after six months of coding, my imagination has run dry.

Anyone have any cool ideas for maps? Nothing too complex, and even better if the're playable
