'Life Drawing 5' by algaegoblin
Do you know how to sketch human figures but do you want to refine your anatomy skills? Or do you not know anatomy at all and you are tired to trust your imagination? Did you notice you create disproportions in your drawings?
If you are aspiring artists and you already have your own style, you might as well believe you have no need of a guide, but you are wrong. Before exaggerating human proportions and begin to have your own style, you first have to know the basics. 
This little guide is the result of an accurate research and 5 years of high school of art, and it's created for all those who want to learn something new or just make a useful review.
For those who have already studied art, my suggestion is to go to step 6 or trying to repeat all steps in Digital format. 
STEP 1
First of all, if you want to learn faster you should draw using traditional tools.
