Well, my reviews so far:
Tree: Beautiful use of DoR. The structure you used for it makes me want to play your quest! The only "but" I have is that particular combo error on your waterfall, I suggest you should have used a layered grass on it to make it unnoticeable If I weren't participating, my vote would have gone here.
Master Maniac: I see it's for your hollow quest right? A pretty solid screen, but it's kinda too symmetrical for me. I suggest you give it a more "ruined" feel to it, like a thousand years have passed and that building is, well ruined. But however, another solid screen and I like your character!
Avataro: Damn, that level was hard (Not). Something new introduced to ZC and quite original if I might say Nothing bad or better you could do to it.
Charizard: I like the GB Pagoda you went for there. And the palette helps the shot increase it's beauty. Nothing much I can say more about it, all but good job!
SirKazuma, Fireblast124, LunarRedMage and Geoffrey: Who copied who? Well, since all look like Charizard's/Shane's shot, I can say that well, great job on recreating! I can't say too much since all look alike, sorry.
Franky: A solid cave shot I could say, but the bridge tiles kinda give a "style clash", but that's not important. Also, is that a Phantom Hourglass perspective kinda cave? If it is, I love it
Demonlink: Too bad for you, too much orange, who cares about autumn? I could do better than you did. Geez, thanks for making my eyes hurt XD
