Null'd for obvious
reasons motivations.
CastChaos: You are a master of water, man!
Darkspawn: An ordinary screen topped with a nice rip. However, it looks strange in top view. Plus, what is Sigma there? A boss? In MMX5, you could hit only his mouth, but it would hard now to reach that part...
Evan the Great: Nice forest, I like everything there, especially the trees and the light.
Majora's Wrath: Unique tiles, okay.
Nuvo: Extreme nice wooden structure with eyepleasing palette. My only complaint is that the bridge part that leads from the north bridge to the south bridge looks vertical because players got used to that tile is a "mountain stairway", but in fact it is horizontal. Maybe you should use some kind of plank instead?
As for the comments on my screen...Nuvo! That water isn't meant to be fully transparent! The depht and flowing speed of water enables it to be blue, plus I need to represent somehow that it's
cold 
.
Somebody said that the minitrees look strange on the bush bed. Well, no u! It's my unique idea!
Some other said that the springs are strange. Well, they are needed from every point of view. Detail, story, etc...
