I like maps, they're an odd comfort in a world where your phone could march you to your death off a cliff and none would be the wiser. Which is, perhaps, why it feels so strange when I doodle out my own.
Being cursed to only be able to take things seriously about 27% of the time (whatever you do, don't steal a gypsie's trombone, they're very protective of their horn section) I can only get in a few story related landmarks before I'm adding inside, outside and inside-out jokes.
But to the meat of the matter at hand, this was the drawing I began with. Black, white, lots of scribbles.
The next step was color and lots of it. This took only around 35 or so layers, I'm doing a lot better than last time when I suspect photoshop had dreams of strangling me with its lasso tool.
