Not too shabby!
You got some decent animating talents there. Sprites and easy to work with and your slowly using them to your max potential. Just work on different camera angles other than 2d side scrolling action, The amount of effects you put in, try to use some of your own effects , my personal favourite is lightning you can see what i mean in my Chrono Trigger flash movie I made 5 years ago. And some plot development, clearly here your jus screwin around with sprites to make a dbz style battle but put in a plot wit all those tips and you got yourself close to Top 20 of the week!
