For the first couple seconds, I thought you did a test shot for Robot Chicken! For something like this, I would use reference footage. Basically, record yourself at the framerate you wish to use for the final animation. Then put the video on YouTube. The problem with this you can't tell how many frames you'll actually need. That's why I'd recommend putting the video into Sync Sketch. Then you can scroll through the video frame by frame, and refer back to this when animating.
Hope this helps!
