Figuring out Details on the Body

Hand/Arm Studies and Mapping out Zspheres

I struggled with figuring out how the hand and arm works so I spent some time drawing up some studies. I wanted to see how they hang. I might model my character with fists though. I'm not too sure yet.
I didn't want to dive into modelling my character straight away without figuring out how his body works and the basic shapes that go with him. I decided mapping out the Zspheres before even touching the program would help me a lot. And it was the best decision ever.
