Furion:
Yours is the best-designed screen, but it the palettes are a little too high-contrast. Specifically, the darkest browns and greens are both a little TOO dark compared to the lightest. I would lighten at least those two individual colors.
And this seems to be a ZQuest shot, so there's no subscreen or sprites. Bad.

I realize you're doing a lot of great things with the Classic set, but I think you're reaching the tileset's limits. I know you probably have a higher opinion of Classic than me, but I think if you improve it much more you're going to have to end up redrawing things into something different from (and BETTER than) the original Classic. I know you're capable of it, but showing those fancier NES-style tiles next to Classic Zelda tends to cause a bit of a clash. I think you'd be better off simply pushing Classic to its limits (which isn't very far) and leaving it there.
And again, there's no subscreen. I don't like that.

But at least you took this shot in the ZC player, if the presence Link is any clue.
As for this screen, it's a little too busy. The rain in particular doesn't look good in a screenshot. Rain tends to have that problem, since it doesn't FEEL like it's obscuring that much when it's moving, but take a still shot and it's really hard to see what's behind it. Regardless, you might want to thin you rain a bit, because it looks extremely difficult to see through even in-game. Also, make sure you have a very dark palette whenever you use falling rain. The best rain palettes are so dark that they don't look good in screenshots, only in-game (the player's eyes adjust).

Heh, not really gonna comment on this screen since you just churned it out so the contest could go on, but I will say that it's nice to see a complete LTTP subscreen. LTTP subscreen graphics are not terribly impressive, but ZC is now capable of recreating most of the LTTP subscreen layout, so it only makes sense that someone should do it. Did you do this yourself or has the LTTP tileset been in further development?...
Personally, if someone's going to churn out a shot like this so a contest can start, I don't see any reason why we couldn't just have a two-person contest. Are we worried that it'd be too cutthroat?...

Anyway, I voted for Furion, though I have some misgivings with both of the first two shots. I believe I'm going to withhold my rant about it until later, though, in another topic.
