Ohh my goodness. I just opened all the unread threads in tabs like I always do... and this sweet animation shows up from nowhere. I read the title, then gaze at it for a while. A few minutes, actually. Around three or four. Then I read the post, spot the signature, and finally realize who the hell made it.
Welcome back, honored warrior of the pixels! We've missed you. Well, I have, at least. With Tsu and Bruce all back again (again (again?)), I even imagine my mind painting the forum a gentle tone of blue... Ahh, nostalgia.
Anyhow, really nice animation. Powerful and otherwordly, as templargfx put it. Say, have you ever seen Otogi (or Otogi 2) for the Xbox? This animation reminded me of parts of that game. It's got some really nice attack animations with dramatic, Japanese timing, such as extremely powerful sword swings that just stop suddenly once they reach a certain point - exactly like his forward motion. I love that! Actually, I think I should study the animation in that game some more and see if I can apply it to traditional animation sometime...
I do disagree with the people who think it looks like he'd jump. The entire animation - the whole concept actually - is stylishly exaggerated. It makes perfect sense to me that one would crouch down like that if the following attack would be powerful enough to make one's entire body slide forward several feet. A jump would make it look more like something from, say... one of them old Karate games for the C64/Amiga/NES. And I really like the exaggerated otherworldlyness, so please don't do that!
