Life drawing has always been tough (am I preaching to the choir?), but the first session of Glen Vilppu's 12-week anatomy course at the Animation Guild has given me hope...hahaha.
Anyways, he gave us some basic proportions and easy measurements that REALLY help you construct the model on your page, not just copy everything you see. I'm really glad I get to take a class with the master, and I'm looking forward to the next 11 weeks!
In these next ones you can see some of the measurements I'm using, as well as more of the underlying bone structure of the model.
