Well...
I would suggest that you learn how to tween. This video looks as if it was frame by frame. That is so time consuming.. You should do a favor you and the viewer and take a look at some of the flash tutorials on the site. Tweening not only saves you time, but it makes your film look more fluid and natural. You may also want to raise the frames per second to 20 or 25.
Don't give up!
Always improve!
