Moo2wo - Awesome screenshot. I really love what you done to the original screen and I really have no criticisms here. Amazing job.
Joelmacool - That's some good global warming going on there. I like how the sand looks, it's kinda like a tideline or something which shows how far the ocean goes inland. Like with Moo2wo, I got no criticisms here either.
Etheradia - Looks nice, but there are quite a few issues I have. First, the top halves of the trees don't have the same ground as everything else, so you could probably put some sand under the top-half of the trees. The mountain on the top-left looks really weird with that tree. I would probably just get rid of the tree completely and fill in that space with mountain. The shoreline looks neat, but I noticed several missing tiles on the corners of the borders. The water looks cool but I would honestly just get rid of the water tiles nearest the ground, they look pretty weird when it's not a straight line, so you can probably just fill the water with just one kind of combo. Overall, it looks decent but there's quite a lot that can be improved.
Theryan - Nice work with this shot! I really love the waterfalls coming out of that mountain and the different layers of water at the bottom. Just like with the first two screens, there isn't any criticisms can be given. I really love how this one looks.
I voted for Moo2wo this week, with either Joel or Theryan in close 2nd.
