For some reason, I tend to love the roughs more than the cleanups, 'cause in a way, it kinda tells some sort of story with how each frame is drawn. But y'know you're work is as great as ever. Keep it up.
I love the fluid feel of this! I've always had trouble getting inbetweens to stop jumping/jittering around. Is it something that just comes with practice or were the specific exercises you went through for this type of stuff?
This was all done digitally on a cintiq, so paper registration isn't an issue. But believe me, there was jitter happening. You just need to go in and refine the tweens until the jitter is smoothed over. 2D animation (for me anyway) is about 1/3 creating, and 2/3 refining. As far as specific exercizes, the technicalities all boil down to proper spacing and motion paths.
