Kivitoe - Looks like a pretty standard shot, and I like the simplicity. Though I'm not sure on using ice tiles for an overworld screen like that. Maybe if the palette was something more snow-like then it would suit more, but here it doesn't fit too well IMO.
ywkls - I like the concept of what you got going here, but I feel like there's still quite a lot to improve on. For example, I feel like there should be more variation with ground detail, especially with using different grass tiles and using different slab tiles. I also don't really like the use of fences being used as walls. It feels too straight for me and probably having something like a mountain instead near the top would make things look better.
Linkle - Nice screen here. I like the dark atmosphere you got going on here, and the screen design is nice and simple. The only thing I don't really like is the use of floor tiles being used on the ceiling, which looks kinda odd to me. Probably using different ceiling tiles that don't look like floor tiles would look better. Other than that, nice job.
Joelmacool - Probably my favourite screen this week. I can't really see any issues with this one, and I love the design and effort put into this. The touches with the water is really neat too.
Plutia - Pretty nice shot. I really like the cloudy background here and the screen is nice and simple. Like with Linkle's screen though, I don't really like the tiles on the ceiling, they don't really suit the screen for me IMO and could really use different ceiling tiles that can blend in better.
I voted for Joel this week.
