You have talent.
GRAPHICS
With a bit of tweaking and practise you could become a pro .. but increase your smoothing. Thats the problem with all these movies. You have the ability to smooth the paint, but you don't. So it appears lumpy. Also, practise your walk cycles. It might pass, but try to get it right. Left leg raises, moving forwards, the right leg 'slides' back, then its done the other way round, then it loops until the person stops walking, all the while the arms going up and down (you got the arms right). Also it was a bit slow paced. When its slow-paced fighting, its dull and .. er .. use smaller brushes.
STYLE
Don't know what to put here. Well, its stickmen. I like stickmen, but use smaller brushes and make it less lumpy.
SOUND
I didn't really like the music. The music was the sort of music you might have in a fast-paced fight, but in a slow-paced fight like this, try .. I don't know any music that'd go with something as slow-paced as this.
VIOLENCE
No blood, but it is a fight.
INTERACTIVITY
Play button doesnt count if you ask me.
HUMOUR
None, but I dont think you were aiming for humour, were you?
OVERALL
I have a list as long as 10 lorries on how this could've been improved. I'll tell you a few from these many improvements: Smoothen. Lengthen. Quicken. Use a thinner brush. Thats just four of the probably 5 million possible improvements to this movie.
