The goal was to take the walk cycle from before and re-do it in Adobe Flash to learn how the Flash armatures worked. It was a struggle, but I finally figured them out (after re-rigging my character numerous times) to the point where they functioned for me. I added the bits and pieces to get a little more practice in.
I preferred the hand-drawn method better. I had more control and could fudge more things, while this ended up feeling a little stiff. The Flash armatures felt like they were just not quite there yet, but I feel like I could end up using them in the future and be happy.
