Moosh - Nope, don't want it.

That said, it's not a bad shot nor bad design, although the mountain tiles look sorta like a wall of trees that are super-smooshed together, and something feels off about the grass, but the design is good.
Keiichi123 - I really like it, and I almost voted for it, but there are a few issues. The fog for instance looks unnatural and discolored, and just above the bridge and just outside the fog there appears to be a tile error on the cliffs. Also, what are those three circles on the left of the screen, to the right of the tall grass? O_o
Cukeman - This one stands apart from the other entries, it's complex and not cluttered, and, well, it just looks good. I really like it, so it got my vote.
Dragonite - This one just feels too familiar to your other works. Like, it's very similar to another shot you've released, or at least feels that way. That's not to say that it's bad, but it just feels like I've seen this sort of thing before. It is indeed a good shot, though.
