Just thought I'd share the current status of the island map.
I'm thinking a monochrome sepia gives it an appropriately old-world / pirate / steampunk vibe. I'm producing it at 300dpi, A3 size, so it will make a decent printout when it's completed (maybe A1 - 150 dpi or A2 200 dpi), that works pretty well as a prop map for games.
Needs more work but it's getting there.
There will be a widerscale map also, showing the position of this island with regard to the archipelago, and then perhaps a globe depicting the archipelago compared to the empire of the old world.
