I try to study anatomy, but all those details are overwhelming. how do you deal with this? going one by one? (study the cranium for a time, move to the torso, etc.) when I do so, I still have difficulties putting everything together.
I know that I need to draw a lot, so it will get into my system, but I want to do it effectively.
should I study the skeleton first and then move on to the muscles? like building layer on layer.
I don't have access to life drawing classes atm, so I need to stick to skelly software, anatomy books and the internet in general.

any advice?
