Not a bad demo reel
I suspect you made this to try to get clients and get into art school right? RIGHT??? That or you're very VERY bored. Either way I like the music you put with it. It gives it a very Adult Swim / Cowboy BeBop feel to it, and for some reason that really fits your style. Keep it up.
The animation itself (not the video translation) in some areas was a bit choppy or too...repetitive. You criticize DBZ a lot for having very repetitive fight scene animations and in some areas you've done exactly what they do. Animate a few frames and press repeat. It's not bad for background shots, but when you just pan the camera so we can see it 20 times it become very noticeable.
Just some food for thought.
