I'll throw my vote in for this to show support for the mapmakers but I really feel underqualified for this as I have little to no experience with rpg's so I'm not sure what makes a good map in that respect. I guess they don't have to to be rpg maps but as most seem to be it would be best if they had utility in that respect.
Anyway, from my limited experience I'm going to vote for Map Vandal's map. Purely because it looks good, I like the style and it looks like it fits the brief. I liked all the others too, especially Jaxilon's, which it was the main contender against Vandal for me, and Euio's, although I'd like to have seen more work on that. It looks like a preliminary sketch for something very special, albeit a very nice sketch.
