As this was a dungeon mapping challenge, and me being quite the traditionalist as to what I personally think is a dungeon map, this limits my voting down to a few people who I believe actually hit the criteria set in the challenge. Whilst I liked the other submissions (tainotim and eelaeg) and think they looked great, they were for me more illustrations than maps and fell a little beyond what I personally would call a dungeon map as opposed to be being some digital artwork (although very nice). Similary with Carbus, the presentation and display of the cards, the details of the system, the mechanics behind the game and the narrative text on the cards were all really well done and thought out... unfortunately for me the maps were actually the weakest element.
So that divides it between Bogie and KenG for my vote.
They're both very similar in style, using some dunjinni type elements, and they've both been done very well. But I'm gonna give my vote goes to KenG, primarily because I prefer the layout and thought into his dungeon design and think it would be an interesting environment. Bogie's looks pretty good, but the layout was a little less inspiring for my personal tastes.
Great entries by everyone though.
