Needs an attack slam animation that fires all at once. And the Death animation looks terrible, it definitely needs dust. And you could have the row of cannons split in half, it would only take a few extra polygons to cut that board in half. It also needs more teamcolor. When your teamcolor spot is tiny, you need it in at least two places. You also may want to have the rear end lift slightly during the walk animation so that it's rolling on the front wheels without dragging its ass on the ground.
4/5.
