Yay, memories!
The animation was quite impressive. Original audio use really got me remembering that episode - one of my favourites, for some reason. Though the first is still the best, in my opinion. Anyway, that's going off-track.
The animation was very nice indeed. Especially the grabbing-grimmjow's-arm bit. Like all anime, there's always a little choppiness going on, but this was plenty better than various 'professional' animes I've seen. That goes in spite of the art, though.
Now it's true that the anime style doesn't exactly allow every angle to be drawn non-weirdly, and I know that, even in bleach, the character's faces turn out really weird on occasion, but a few of the faces in here made me cringe. Dunno if you could've done any better with more effort (I certainly couldn't), but it was a slight nag.
Thus my 8 is handed over to you - that's a splendid overall right there. I do hope you keep developing your animation skills!
