Needs work, but it's getting there.
While effective in producing an emotional response (now I want to go out and rescue all the bunnies in the world, dang it!), the animation was lacking. Actually, there wasn't much animation...just a collection of still frames. That technique can sometimes be pulled off, but usually with some kind of a transition between scenes. It's a little strange when POOF! There's a truck. POOF! There's a man in the back of the truck. POOF! There's a bunny standing up. POOF! Now he's lying down. There's something almost Atari-esque in its simplicity. ;-) So I recommend you work on true animation. Frame-by-frame animation would really complement your drawing style.
