Your doodles are delightful maps! We'd like to see more, if you have some (or as more boring classes happen :-) ). Thank you for posting good content right with your first post - have a smidgen of rep.

If you created a collection of little clusters of those isometric buildings and castles, I bet folks would use them as brushes for indicating towns and cities. I like that look, but I'm not much good at making picture-representation cities.
