hmm
I don't really like anime at all, so i'm going to be unbiased and just review you completely on graphics and style.
The graphics were fairly done, a little rigid (not the typical smoothness i'm used to) and the style was interesting from what I could see of it.
On the other hand, even though it was a trailer it was still very short and left nothing to be desired... which is kind of the point of a trailer, but still, a fairly decent job.
