Hexcrawl Jump Start

Even though my players have a ways to go yet to finish this ad hoc dungeon, I'm chomping at the bit to start planning out a hexcrawl once they leave. It will be a wide-open sandbox-style campaign, largely ad libbed. I surprised myself; I'm not any kind of an artist, but I think the map I doodled here actually looks okay. It's their village (Hommlet--no relation to the AD&D module; I just like the name) and a bit of the surrounding area. The dungeon they are presently exploring is "Valhavoc Dungeon"--they don't know this name yet, but "Valhavoc" is the magic-user who created this horrible place, a mere 1,000 years ago. Heh.
