I voted for Devin Night's entry because it was indeed map-ish and very well presented. I would have liked a key for the various rooms but I guess someone who wanted to use it can do that themselves.
It was very hard not to vote for DJ's entry. I really loved the way it looked and while I guess I could see it as a side view map it's not my favorite direction to look at one. That said, if I had to have one of these on my wall I would print DJ's, it just looks wonderful.
Mrmox - A fun entry, I enjoyed going up and down the levels.
GP's - as mentioned more of an illustration but still nice.
Imm - good work on the 3d stuff, you will probably have this down really well soon if you keep at it and then everyone better watch out.
Neon - As stated, a nice Old School look
Siq - Nice creative entry albeit a pretty simple looking map which is exactly what the Pip Boy looks like but hard to vote for against DN's more finely detailed entry.
