I really like the style and theme of this. The music helps set that, but your animation style is what really drew me in. Some of the effects you used were really cool as well, like that underwater effect in the very beginning. How'd you do that? The explosions were really clean and fluid, too. The only thing I don't like about this is how you reused some clips, but I can see why you did.
Overall you did a great job with this. There's a lot of tweening, but your nice animation style makes up for it.
