Well, it's Urd that's doing the open mouth grin, which with a closer look doesn't seem to affect her face the way you'd expect it to. Her eyes.... red-purple catseyes?
I'd say Bell, needs more of a smile on her face, a shine in her eyes and a good smidge of looseness in her stance. Something that they all could probably do with, and is possibly something difficult to implement without using motion capture. Although that's something the Kinetic hackers are working on.
Apart from that and their eyes not seeming to be looking at the cameraman, I can't see anything else springing out at me.
