Greywulf's sudoku dungeons guide. It's definitely a good tool to jump start a stalled brain.
Next, I inked it before scanning it. Before now I had just scanned the pencils and skreeked the contrast curves in the computer to make the blacks blacker, the whites whiter, and give it that lemony-fresh scent. I guess it's OK but if I ink again perhaps I should get a finer pen and a little better quality of paper?
And as you can see, I followed Tim "Risus Monkey" Ballew's idea of writing words in a few of the rooms to serve as imagination fuel. I just used the table from the sudoku dungeons post as the source 'cause I'm terribly lazy right now.
Something I need to avoid in the future is placing a secret door on the edge connections. You're left with either half an "S" or an ugly white strip breaking up the fill pattern. In any case, it's yuck.
