it's really not that bad for a first flash

Although this is obviously noobish, it's really not that bad for a first flash. Often, first flashes are horrible or short. This actually has a semi-understandable story, and a decent run. The text was small, and went by fast enough that it was hard (impossible) to read, but I could still follow the story. ...or make up my own.

All first flashes should be like this or better. Thank you for actually caring, and not submitting a crappy first flash! :)

Not too shabby. Keep practicing.

Not bad for your first flash!
Some suggestions:

1.Dont be afraid to speed up the movement. I'm sure your a Naruto fan..So we both know, they dont throw things that slow.
2.Polish up your environment a bit!
3. Experiment a bit with frame by frame animation. You have a pretty good handle of tweens , but now its time to try something different.

good job overall!

Needs work, like the speed of the thrown knives/shurikens are way to slow and there is an overuse of metric tools to create the background. The attack thing with the hands would have needed a few extra frames too, as it's hard to see whats happening. Not a bad try, but it needs some work.
