Really good for a first animation. Frame by frame backgrounds make up for the lack of detail. Keep up the good work!
That was some really really good amateur FBF. Choppy or not I still like this, wish it was longer. I also loved the fire fight at the beginning.
Some of the animation was choppy, while others were smooth. It looks like you allocated the time spent animating into important scenes. Maybe spend more time planning out your animation.
not bad, but keep on practicing, because your animation is still very choppy. good luck!
