I didn't like the castoring on the tail wheel. Wind drag would keep it mostly straight, and if it's mostly straight it wouldn't be sideways on impact (and wouldn't spin around wildly). The general motion is okay, but what this guy is good at is surfaces and textures, THOSE are sweet as hell. He uses camera motion well, as well as camera blur and the like, but I don't like his motion in some cases. The perfect split-second 180 turn with little lurching or tilting at the end of the film spoiled it for me.
Can't fault him on his bad human motion, because hardly anybody can get people motion down well, but that alone should be enough to say "this is 3d, not real".
I checked out a few of his other clips on that page. The texturing and sounds are really good on most of his stuff (didn't check 'em all, but I liked what I saw)
