I like this, i really do. do your viewers (and if at the least yourself) a favor, try some full body animation. i see some good ideas in your art work that i think would be great.... look at Ninja vs demon and other stuff by Sunny-GO for ideas .. it really helps and i think your great
not bad, Now you just need to expand your horizons.. Add more to the background so that the stick man can interact with it. (e.g. Tree's and the stick man could swing on a tree branch or something, Or Stairs he can run up, or walls he can jump off and run up etc.). Breakable backgrounds are also nice to look at in flashy stick animation (e.g. crates, Rocks, Floor, Walls, a whole building etc.). background interaction and stick man mobility is what makes a good stick fight flash.
well, it was alright, but kinda boring, you need to add flips, and spins and backflips in dis sht maaan
a fast massacre
