Wow...
This was really good in fact this was great a few words though try making the stickmen in a smaller paint brush so you can diinguish them better, try adding some color to your characters you know so we can keep track of whose who and finaly i know this is your first flash but before you submit your next one please take a good hour or so and make a Main menu. People dont think a main menu isnt impotant but it can really add some luster to your animation. I hope you dont take all of this badly im just trying to help im an stick fight animator myself....so keep on animating youve got a knack for this sorta thing...
