Really, only one loading is necessary. Since the Newgrouds preloader comes with text that says "LOADING" - why did you put more text on that said the same thing? A bit redundant. Ok, I'm gonna watch now.
I liked it! Two things - Firstly - replaying it, the music continues to play over itself. You should put a stopallsounds at the end of it to stop that - hearing the music playing over itself is annoying. Secondly - Nice job on tweening. However, the feather should slow down as it reaches the ends of the arc - you can accomplish this by easing it (using the "easing" control).
