Oy. I can see what you did here, or at least try to do, but arrangement of the tiles don't work entirely with the perspective. Something this large really can't have the depth of a piece of cardboard; If you give it more of a ceiling and use less tiles designated for a sideview perspective, it might work. I know the ruins in Z1 were also flat, but the size of them didn't make it so apparent.

It's a good start, but the mountain tearing through the screen like this breaks the screen's balance. Cliff tiles - Specially the GB ones - tend to be kept at the screen's or area's edges, as poorly-placed ones tend to break the flow of the design. Also, the fact that the elevation is kept consistent at two elevations doesn't help, and perhaps if there were multiple elevations in this screen, it would help even out the sharp change in the cliffs.

Its-a me!*
The only ones I could really get into were Goriya, Orin XD's, and Shane's.
The other ones look like they were built just to win a contest. not for a quest.
I voted for Orin though.
Well, it is a screen in a quest, I didn't just build this for kicks. I take my time with map-making and try to avoid creating what I call "filler screens"; nothing frustrates a player when they have to walk through so many screens to get from point A to point B in the most indirect and monotonously difficult way possible; and as a result, I don't intend to make everything big in this quest. Instead, I will be aiming for practical and somewhat logical dungeon designs and purposeful lands. It may be a slow process, but my philosophy is that for the sake of time, atmosphere, and backstory, a screen needs to serve multiple purposes, and not just something that's between A, B, C, D, and so on.

The left half is pretty good, but the right half concerns me. GB mountains aren't good for steep cliffs such as what you've got, and it can start feeling like a waste of space to some players. Also, it's not often that you see a cheese wheel floating down a stream...
Shane
If I had not entered this SotW my vote would go here. It's a well-balanced screen that keeps within the capabilities of the GB set and has an all-around great layout.
