Just letting you all know that I'm working on that animation you voted for, but it's likely to be a while! I've been doing research and trying new techniques just to do the best job I can! Here's just a small example of how things are coming along. Credit goes to Dark Violet for giving me the idea for using a sine wave (cobbled together out of the ellipse tool) to give the tail a more even flow (after I spent hours trying and failing to animate the tail in an acceptable manner.)
This is going to take a while, but I promise it's going to be good!
