It's short, but hey, it's your first flash. It was simplistic but this made it stylised and the animation was smooth, you have potential :)

For a firsty, you've certainly got vision. Unlike most other ones, you actually put the effort to make backgrounds and animate legitimately frame-by-frame, not abuse that cheap-ass tweening. Keep working at it. Also, use a preloader to make it more professional. There's a selection in the Downloads section on the site for free.
