>>5764862Try and get a feel for bones and how they bend and change the form in different poses. Take the collarbone for example. Figure out how it actually is shaped instead of just a line with a u in the middle.
It bends with the ribcage and sort of goes up and takes an oposite bend before ending right on the top of the shoulder. Sorry for the scuffed explanation but I don't know the latin names..
You have a good foundation and now from these simplifications you can go more in depth.
You'll get there.
