I am going to begin this tutorial by addressing one of the most commonly asked questions that I receive: how to draw women's breasts (heh, I never thought I'd actually be making a tutorial about this.... ^_^). One of the most important things you should consider is to make your subject look natural; you can draw an attractive female without making her look like a "silicon implant ad," as a friend of mine put it. ^_^ The main problems people seem to have with drawing breasts are the shape and the placement. A lot of artists (professionals as well as ametuers) make them look like balloons that have been taped onto the subject's chest; this is hardly a natural look. If you look through figure drawing books, you'll see that they are more like halves of a sphere or overturned teacups rather than balloons. Now, note the position. Imagine a central guideline that runs down the center of your subject's body, as shown at the left. The breasts are at 45 degree angles from that center line, and are about halfway down the chest (shown by the red diagonal guidelines). Be very careful not to draw them too close together or too far apart, or too high on the chest; these are commonly made mistakes. As you will see in examples below, this basic rule of the 45 degree placement will apply to pretty much whatever pose you are using.

Here is another pose, showing the torso from a front view.Note how the breasts are still located at 45 degree angles from the center line of the body. Oh, also take note of the shading. After looking at various examples, I find that

shading in this fashion (rather than just following the lower curves as you would shade a sphere) makes them look more natural.
