Lags alot dude
You've set the frame rate too low and your animation , as a result , looks too choppy.
Thus, you didn't compress this flash at all so it is far too large for its size - 9.6MB is too much for this! Because you didn't compress , you made the viewer wait unnecessarily too long and this will negatively impact your score.
Furthermore, I'd like to point out that you need a preloader. Animations without a preloader are a telltale sign of an inexperienced animator. This also hurt your score.
Finally, try tweening . All of this FBF was unecessary for this animation. Not only tweening would've made it look better but also would have saved you time. Generally, IMO , you should only use FBF for special effects or fight scenes - other than that it's just a hassle.
Hey I hope this helped. Good looking man.
