I have to say congratulations to everyone who entered, I didn't expect to see so many entries that are actually fun to play and have the potential to be really good maps, so if you took part give yourself a pat on the back, you did well.
Here's my shortlist in no particular order:
cp_ezekel_72_1
pl_ym_72
cp_frozen_72
koth_grazr_72
pl_leminnes_72
cp_hanz_72
plr_zhan_72_02
cp_ravage_72
koth_psy_72
koth_reej_72
EDIT: I should add that I'm judging these as maps that I'd most like to see finished, by no means do I think they're perfect and some even had some glaring errors, but I felt they had the most potential to be real stand-out maps. When I get around to it I'll leave some more feedback about them, just started a new job though so I have v. little time though right now.
