I'm not that much into the spaceship-alien-laser-explosion stuff, but this piece in particular is really good. There's a significant sense of depth and the planet makes it more dynamic. The city however, looks a little blurred. I don't know if that's intentional but cities are usually about very sharp edges so that's what makes it a little odd. I suppose it could be like sand going by (if that's what you were going for) but... well, I don't know.
Was the movie any good by the way? Haven't seen it yet but I most likely will, soon. (:
