Good...however...
I hate to sound like an ass, but it must be said.
If this is your first animation, then its not so bad. Here is my review.
Graphics: 3
Why:
Overall, the graphics are just stickmen fighting. There is nothing much that had a lot of detail. Although stickmen can be used as something like "Stick Fight"; you don't give much to hope on. Spend more time on your people inside the flash and try to make some rooms.
Style: 1
Why:
The whole Dragonball thing has been done to death. Complete death. Please use more originality with your next flash. You'll get more points that way.
Sound: 4
Why:
The sound was not too, too bad. Use something else next time. Linkin' Park, as said before is rather old.
Violence: 7
Why:
You have a lot of interesting concepts for future conflict. This is what I liked the most out of your flash.
Interactivity: 0
Why:
Obvious.
Humor: 0
Why:
Obvious.
Overall: 3
PRO:
1) You do have some good hints for future conflict.
2) You used the music rather well; although overused.
CON:
1) Poor animation
2) Couldn't really tell what was going on. It was all over the place.
How to improve:
1) Focus more on the animation.
2) Use better music.
3) Define a good storyline for your possible series. Doing so makes the whole flash creation process a lot easier.
I hope this helps. Good luck!
