That was actually....really good. You did an excellent job with the voice clipping like, really really good. It actually sounded and looked professionally done as there wasn't a single moment where your sketches didn't flow properly with the voices. The only thing that sounded a little off was at the end with the next weeks episode preview thing where the bad guy's name/description changed from whoever it was originally to Vegeta, but it was still pretty good nonetheless.
Your drawings of the various characters was surprisingly refreshing and actually gave me the feel that I was watching a real Dragonball Z episode, so, kudos to you. The animation itself seemed to flow smoothly, so no critisim there.
I would seriously enjoy watching a "next installment" of this first episode. Btw, Vegeta pwnz ur soulz.
