In this tutorial we learn the anatomy of the arm for drawing. Although you may look at an image that you want to draw, drawing it is completely different with pen and paper. Learn the different types of bones that are in the arm to get a better idea of where they should be located at. Once you draw the joints and the bones, then you can connect them all and have far more details. It may take you a long time to understand how to draw the arm and all the parts, but you will gain a lot of knowledge and draw much better!
