Akatsuki? "Sunrise?"
-Little to no actual animation
-Music that was too loud
-Unoriginal, overused characters
-Little attention payed to script writing
-Zero voice acting
-Tenuous grasp of standard drawing techniques
All these are characteristics of animators who have not practiced enough, and by the looks of this animation, you need more practice.
Now I know I may sound harsh; you're probably new to flash or are 13 or both (since Naruto is predominately enjoyed by 13 year olds). My point still stands: you should practice for a long time on your own before you try submitting things. When I first got flash, I had the advantage of already being able to draw, but it still took me a long time to get anywhere near good enough to make something I was proud enough of to submit to Newgrounds. I made dozens of test animations that only myself and a few friends ever saw, and now I have an animation with a score over 4.0.
It's not a hunch, it's truth: a lot of practice is required before anyone gets good with anything artistic. Flash is no different. Sit down, draw for 6 months straight, and then try again. If you're not ready after 6 months of continuous hard work, I'll eat my hat.
