Oh man, we've got some bitchin' shots this week.
Joelmacool12 - I don't usually like the Pure tileset, but this screen impresses me. I like both the concept and the execution.
GrantGreif - This is a good looking screen. I should probably know what tileset this is by now, but I don't.
Twilight-Prince - It's hard to make a desert screen very interesting, but I think you've done all you can do here. There's a good amount of scenery without overdoing.
Eddy - I like everything about this screen except the one-tile doorway on the right. That pattern and color doesn't seem to match everything else that's going on.
bmc10011 - This is a creative use of the GBC tileset. Is the fog animated in ZC? It almost blends a little too well when it's motionless, but I think it would be great if it was animated.
Logos - I always love seeing the classic tileset re-imagined, and this one does a good job of it. Normally combining borderless and bordered tiles makes things look strange, but you've pulled it off somehow. I'm not a huge fan of the coloration of Link though.
Despite all the obvious talent here, Eddy's shot won me over this week.
EDIT: Actually Eddy, I was going to comment on the lava-to-floor thing as well. I originally thought it looked strange, but if I remember correctly, that's how the Oracles series handles water in dungeons. So if you're meant to be able to fall into the lava and get hurt, I think it works. Otherwise a border or something might be better.
