Nice.
im not sure who was who. but that redhaired guy had "spike" written all over him. not a bad character frame to base it off. i mean i consider that alot more a tribute than anything close to a ripoff. excellent animation style there, some parts could have been a little smoother. even 1 more frame of animation per movement could have probably made it perfect. i notice alot of Watanabe influence there in your work. im telling you all you need is make those fast animations smoother, and you got something great, possibly even epic going on here. i mean if you think about it, if you could possibly produce something to match the quality of Watanabe's works like Cowboy Bebop or Samurai Champloo... it would make the true power of Flash reveal itself. the ability to easily and eventually effortlessly compete with traditional animation.
I can see you got the talent, with the effort in, you can seriously make a name for yourself on the net.
