Damn, that worm is just out of reach. Boo.
Staying with my current underwater mood, I decided to create a rather frustrated - but hopefully cute - crab.
I created a lengthy WIP for this as well which includes a bunch of the animation-in-progress as well. Somehow I seem to have hit a hotkey which turned on my webcam, so two-thirds through you'll get a lovely peak at my wall. Hopefully the WIP is useful for demonstrating my techniques.
