Billy:Way too basic. Everything is at 45 degree angles. I prefer it when GB trees are less patterned. Also, those are really old tiles; the black outlines are starting to look pretty dated. Being a ZQuest-only shot doesn't really help.
Joe123:Yes! DoR cave tiles used to their full capacity.

...Well, mostly. The perspective looks a bit weird in places where you've put two objects with conflicting angles next to each other. Also, that ravine at the bottom is pretty shallow for an over/under bridge. But still, this shot is my favorite overall, taking the subscreen into account.
Voted.
Lithium:A decent shot, but I'd simplify the grassy areas a bit and cut down on the debris. Also, I agree, the alternate palette is better.
lucas92:A good shot for the most part, but a few things bug me about it. First of all, why bother using a log that short in the middle of the screen? It'd work better on a screen border. Also, we've got a big shadow in the center of the screen that's just hovering like a cloud. What kind of tree casts that? Also, it'd look better if the big trees aren't half-covered by a shadow; it makes them look flat.
Molten Onyx:A good shot for the most part, but lack of use of shadows makes it hard to tell what object is at what height. Is that bridge in the center of the structure higher than the platforms on the left and the right? If so, you need some more shadows to bely that fact. Also, the palette seems to need more dark greens for transition.
SerpitaX:Is that dark sand actually translucent water? If so, good job.

It probably looks good in motion, even if it's hard to tell in the screenshot. This screen is very nice except for having little variation in tiles.
Twilight_Knight:Pretty decent custom tiles, though it's a bit blocky, grainy, and in some places repetitive. Keep at it, though! It's nice to see new drawings.
