I saw on a random thread that you like the map for The Rock of Bral. Did you know that there is a guy out there, who has done that map?
There is a thread about the map over at the Spelljammer forum at The Piazza (called Hm, huge map of Bral done in campaign cartographer). Everyone was so excited about seeing a Spelljammer map that they all jumped up and down like a bunch of 16 year old cheerleaders! I gave the map designer a ping and he signed up (as The Man in the Funny Hat) and when he saw how much everyone loved his map of the topside of Bral, he went back to CC and made the Underside for us.
Anyhoo, I think you might enjoy it.
