Yessir, always a lot of trade-offs. When to use a five point patch, when to use a hook, etc.
Hmmm, there is another thing I'm kicking around in my head. I made him less cartoony than I probably should have if I want to be able to use the extreme squetching aspects of the rig, so, I've been thinking about putting him in a super hero spandex suit with an emblem on his chest as an explanation of those "powers".
I've tried to stick to a couple of things that work best for the way I want to rig him. Eight splines for the eyelids, limbs and fingers and twelve splines for the mouth (but, technically it's actually fourteen with the way the upper lip is built). I don't like the number of splines I had to use to attach the ears, but with the added detail it was necessary.
You might be able to get rid of the center spline using some bias adjustment, but it's a lot easier to just keep it.
