This looks fantastic although the videos seems rather lifeless :/
The animals were obviously just a quick mock up to add to the effect but there didn't seem to be any wind effecting tree's, the water seemed far too clear and still, once under water it looked fantastic but in your 1st screen for instance, the water is pretty much invisible apart from the refraction, also when you were flying into the ocean, the water looked almost plastic.
9/10 all up, everything was beautiful and I can't wait to see games done with this engine
PS: 1 thing I would have liked to see would be a fast motion 1 min video of 24h's sped up, that always looks great.
