Applause!!
You have a unique and catchy animation and drawing style. You did an amazing job capturing the style of DBZ fighting into a parody of both sides of the crossover. I take it this is not just a parody on Mario and DBZ, but how a lot of Flash movies these days make Mario out like a DBZ character... I could be wrong, but still, you did fantastic on this movie.
The graphics looked a little cheap sometimes... the yellow focus strip looked like a 2 year old played with the line tool. Then later a black focus strip looked perfectly aligned.
I would recommend you increase the speed of the fighting, or pace up some of the animations. Well, I WOULD recommend that, but its not necessary seeing as this is more a parody than anything. The fighting was well directed in that respect. Still love it.
The sound bothered me a bit through the beginning, but I managed to shrug it off. It sounds like you took a cheap mic and recorded sounds from your TV speakers... eh. You can get plenty of high quality DBZ sounds out there, but you already finished the movie... its probably not that big a deal at this point.
In conclusion, you could go many ways as an animator. Good lord man, hone your talents for fight scenes and you could give Chakra X a run for his money. The only reason I gave this a 9 instead of 10 is because of the butchered drawing quality I saw often. Otherwise this movie is virtually perfect for what it is.
