I picked the Indestructible because I thought it was a very original concept and well executed. And I picked the Blue Pyramid because of the sheer amount of interesting detail. All of the entries were great really and Schwarzkreuz's piece was pretty fabulous but I thought it unfair to vote for it because it wasn't a map (yet).

Also well done to Sathurn with tree city. To get results out of MS Paint is a lot of work and I've always been fond of "world tree" and similar ideas.
