Good
Too much tweening, not enough real frame by frame animating, your camera moves need easing in and out to be more compelling. But you did use lots of good viewing angles in your camera direction.
Tweened shortcutty animation is used predominantly for fixed pov animations where everybody stays pretty much on the same visual plane. Or cute cartoony shit.
Nice work with the guns, but don't rip off Pan's Labrynth anymore. Dorks like me will see your attempts and yell at you for it.
