hi i thought some constructive criticism might be helpful to you.
you can draw well. your style is quite good. but you are lacking in 2 major areas. your storyline was virtually nonexistant. you introduced the first guy as if he was some type of hero but in the end he didnt really do all that much. You shoudl have stuck with that idea. secondly your sound needs work. basically bring the voices out more. and htings like explosions if you have some sound editiing software you can still have them up load without destroying people's ears by reducing the treble. anyway you have promise. spend some time and do out a script. and stick to it. characters are important. anyway good work :)
