I've finished the first of my water geomorphs for the +GeomorphMapContest. I posted the pencil sketch of it a couple of days ago here.
I redrew the basic layout in pen the scanned and added flat grey fills. I then drew a collection of items on a separate sheet so it wouldn't matter if I made mistakes. This also allowed me to carefully move objects around until I was happy with their positions on the map.
It features a baker's cellar that houses a large water wheel that drives a stone to grind wheat. I've not decided whether the Baker is aware of the cultists that meet next door, and the secret passageway that connects the two cellars. I'll probably write this up for the next issue of Oubliette.
