Dungeon of 1,000 Coppers - A Map

Dyson, over at Dyson's Dodecahedron is running a small contest to finish a map he began and fill in the empty areas.  Now Dyson's technique has become something of the standard for hand drawn dungeon maps in the past few years, but what makes his maps great is the way they are constructed with a great deal of verticality, looping and extra entrances - so they're not just well drawn, they're well designed.

Lost Copper Isle

Anyhow, I figured I'd draw up a Dyson style map for his contest.  I have tried to make the vertical element important and use it as a way of splitting up nearby areas while offering hints of thier existence.  I've also tried to use a fair amount of water both as obstacles and to maintain the maps nautical flavor.

The map turned into some sort of fantasy version of El Fraile Island, a sea fort carved out of a rock outcropping.  Now the way I figure it the fort is relatively new and recently occupied by pirates who made a few improvements before being driven off.  Prior to that the whole island (let's call it "lost copper island" was some of temple complex or ritual site for a sea deity and its best if it's some kind of icky Cthulhu style sea deity I think.  The abandoned pirate fort fills only a third of the space with  set of sea caves, a flooded shrine and perhaps some crypts filling out the island.  There's even a little cave for a creepy old hermit in a battered coracle who might be able to impress upon characters the danger or potential glory of the island.
