Too bad you won't finish it.
I really rather liked it. Just one critique on a technical aspect - it looks like you might have used tweening for the head-turns - i.e., it looks like you drew the head facing left, the head facing forward and the head facing right, and used tweening to transition from these three positions. While it's still a great little flash, those particular scenes were a bit awkward as the head shapes morphed and distorted between phases. If that's something you would want to fix, you really wouldn't need to draw every single frame, just two more frames for a quarter-turn left and quarter-turn right. Tweening between 5 frames instead of 3 would go much more smoothly.
Just a suggestion. As you say this is old, you may well have already improved beyond that, which if so, then never mind the advice and good job! :-)
