Are the lengths looks alright here? like arm/legs/torso/head

hands/feet are less of a concern given how small a unit is. Like they basically only need to exist, but if they look off too say so.

the depth of the body and like developing muscles basically is later. I want to get the basic shape right first (and make those damned hands which takes much longer than you'd think, joints seem to be the most difficult part, and a hand is basically a bunch of joints in a small area).

Basically what I'm looking to do here is make a base Human.
Then I can load this base unit and easily scale things like shoulders, hips and what not to make it male or female. Then add muscles and whatnot that makes the unit itself look more unique. But if I build a basic Human and then add a bone structure and make all the weights and rotations and whatnot right on a basic Human it would save a ton of steps for each additional unit down the line.
