Also, tip for those trying to figure out the shape of a body, you can always split the body into parts and "block out" how things should look and join them later.
Here, I have split the hands, neck and double torsos up for more freedom
One of the tougher things about multiarm is figuring out how muscle works. I like to think about what each muscle is responsible for - then if they were doubled how they'd slip under other groups to fit.
I am happy with the "double V" down here but more work needed
