Cortana looks... odd. Like she's missing half her neck.

I'm not entirely sure about the Gravemind. As mentioned, it's a throwback to Bungie's more gruesome variations, fully realized. I guess it looks a little odd to me because it still looks so awkward trying to talk--maybe if its outer flaps were shorter (and he didn't have that faux fu manchu with the bottom tentacles.)

Still, a lot of really cool stuff, and I think Blur did a nice job with restaging some of the shots without totally going overboard.
