Stick figure animations.
I don't want to sound aggressive or anything, not putting harm to anyone but i have a few things i want to bring up.
First up, Stick Figure animations have been known to be purely based on killing, fighting, war, ect ect. Obviously they are getting better in quality of animation - so ill disregard that.
So if you want to distinguish yourself better from the rest of the many other animations i think you should step it up on your sequel. (or any other stick animations that you are going to do in the future)
About the story line - it seems generic, generic meaning common or often seen. I know nothing much on stories but that does not stop me from saying that but there is always a story on a hero going for the villain. Also, I want to point out that the story does not quite make sense; for example, how does the hero know where this Enemy is, or even how they know each other.
The voice acting is seems like it was not put to use properly; put in halfway through the animation is a bit silly. It's either in or not.
Sound effects/Music - I think that it would of been better if the music was made purely for this animation, now I'm not saying that there would be a perfect piece for you to incorporate into the animation but there is always contacting an artist to help you out or even make it yourself if you could.
That is all I have to say, I hope you keep this in mind.
I am not saying that this is bad, it just need improvement.
