The animation isn't that great, but this is cool as fuck nonetheless.

Is that silhouette in the beginning Hisoutensoku?

Yeah, like in the from the title screen and perhaps mixed a bit with Al's super deformed.
Personally, I think the original rough sketch art of this fanmade opening flows better, despite being less animated.
