Wow... I'm glad I didn't enter this week, so I'll have a chance to say this:
PolygonX8, your shot deserves the win
hands down. 
With so many "runner-up" entries, you really deserve to hear that for once. This shot really looks like it's pushing the limits of ZC on
multiple levels; it is in no way a gimmick shot. Good job, man. Looks like you finally made a real winner.

Other commentary: ...
Snort:Hmm... I'm kinda tired of all this overabundance of lava I've been witnessing ever since I started with ZC.

My mountains use dark green in their coloring, so they don't exactly look right, against such bright red magma. Even more so, having trees right up to the edge. Generally, the mere presence of magma threatens all forest life.
plith:Lookin' good here.

The browns are a little dark and those trees at the bottom are a bit too high-contrast, but nevertheless I'm happy to see the new (or rather, lesser-used) palette.
ML3K:This shot is a bit crazy, and it has some clasing perspectives right next to eachother, but it is at least interesting... and besides being a bit too busy, the design is pretty good.
Shoelace:I really liked your "ghost" idea in the demo, and this is a nice scene. Not a trophy-winner, but a solid entry.
Dart Zaiyder:There's not much going on in this shot (perhaps a few enemies might've spiced it up a bit), but it's a well-designed screen. I like that new small tree there.

Very good stuff. A nice screen for showing off a tileset. Are we nearing another LTTP set release?
