Running Stickfigure on Background

Over the past week, I have been working on an animation with a moving background in Flash.  Moving the background was easy, the hard part was making the stick figure move as smooth as possible and as realistically as can be.  I feel like I have not achieved this goal, but the animation doesn't look too bad.  My prior animations in Flash and even in Pivot helped me along the way.  The onion skins really help you when you are making the animation, they show you where your stick figure last was. Once you get to know it, Flash is really fun to use.
