Day 57: Added a swamp lake and a ship. Almost done now.

During the weekend a friend of mine presented a new role playing game for me that he made. So I followed my inspiration and started making a map for one of the adventures in the game.
I want to make a surreal map of a dreamy pirate world with small details and vastly different regions. So far we have got the dark forest island, the mountains and the beaches. I am thinking a ships wreck on the small island in south west.

Please hit me with you best ideas, both for WHAT to include in the map and technical suggestion on HOW to make it a great looking map!!!
