if you're gonna be making quadrupeds (including six-limbed critters who locomote on four legs) of any sort, for the love of all things squeaky, PLEASE LEARN SOMETHING ABOUT GODDAMN FUNCTIONAL LIMB MORPHOLOGY*.

I have a tutorial in the works for this which will explain it better, but the basic idea is;

ALL OF THE JOINTS WILL MORE OR LESS LINE UP EVENLY.

For example, elbows and knees will be on the same line/pretty close to it.

Wrists and ankles will also be in a similar line.

For ungulates, the knuckles will line up.

I have drawn examples for horses, cows, bears, monkeys, dogs, cats, monitors, rhinos, elephants and hyenas.

Nothing winds me up more when I see badly laid-out critters in an otherwise nicely put together image. I have doodled some common examples, too.

The reason I say this is because THERE IS A REASON LIMBS LINE UP LIKE THAT. It helps make movement efficient and less energy-expensive. There's a whole more sciencey garble in there but I'm too blegh today to type it all out. I'll put it in a ref sheet if I can find it.

*If you're making something odd-looking or deliberately off-kilter, you can kinda disregard this but most vertebrates do follow this basic idea.
