Not much to say. But if we must, we can get into the details. Obviously, a plot is lacking, but we don't care about that for this vid. We saw more of the droids walking than the clones. The droid movements (at least for the B1 Battle droids) are obviously duplicated from one walk sequence and re-timed so there's no dynamic movement in them. Same goes with the B2 Super Battle droids. Not much to say about the clones other than they look like they're wobbling their way into the frontlines.
But the scenery, the improvements to the physically stiff-leg-and-arm plastic Battle droids is to be commended...if only we could get a closer look at them.
I find brick-ified terrain unnecessary. Too many vertices to handle. I mean, it's understandable to have studs for them to walk on, but in the background, they're redundant. If you have a render farm in your arsenal, then it's trivial and you can handle it, but if you only got one computer burning its CPUs to handle a thousand background cylinders and cubes one can barely see, you might want to consider some compromises.
