Good one Mitch

Good stuff, love the second type description.

Cool beans.

Good diagram.

One of the things that confuses furry artists into placing the tail too low, is that us humans have a tail: the 'tailbone'. Our tailbones don't curl out from the back. Our tailbones don't go straight. (We would have to redesign chairs, if they did!) The human tailbones curve in & tuck under, towards the front. It's too easy for a body-aware human to 'feel' that a tail should go that way, rather than straight out.

Straight out is more sensible anatomy design for a long-tailed anthropomorph. And with some flexibility built-in, the anthropomorph's tail could have the options to go somewhat out, tuck somewhat in, and go the traditional wag-around.

I'd tweak the final picture's legend: The base of the spine position isn't anything to do with anthropomorphs being primate based - merely that the tail is what happens to the spine in most species after the pelvis, so it should just be a smooth flow from the one into the other.

The tail is an extension of the spine as it passes through the hips. It's the natural position.

That's true, but it's not unique to primates.

I always thought the tails being too high looks wird and too low looks like the tail is being excreted out.

Exactly!

Glad I could be of some assistance! :)

And thanks for watching! :)

I like the background memes: stop sign, warning sign, green light!

Yeah, an improvement over the original, methinks. :)
