Dimentio - Once again, another really nice classic shot. I still really love those ice tiles and the sense of depth in this screen is really good. Nice job.
Zaxarone - Pretty decent shot. I really like the subscreen, though I do think the screen itself is a little empty with not a whole lot going on. Maybe add more pots or ice or something to make it look more diverse (if that makes any sense lol).
Sheik - Very beautiful shot here. I love the overall atmosphere you're going for and I especially love the use of the BS Tileset. I got no complaints other than the GB roots which look a little odd since I always thought they suited more for a swamp setting rather than a forest setting. Other than that, good job.
Edit: On closer inspection, I noticed that mountain on the top-left is looking really weird and has quite a bit of tile errors. Probably fixing up that mountain a bit can make things look much nicer.
Plutia - I like what you got going here, but like I've mentioned elsewhere, the mix of GB and Koten doesn't look very good IMO. Other than that, the setting is pretty nice and I do like that green palette.
Overall, I voted for Sheik this week.
