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.
Here is one last pose to go over the size and placement. It's harder to see here, but the breasts are still at the 45 degree angle from the center line (which isn't draw in this picture; sorry about that ^_^;). Notice that the leftmost breast is drawn as a half-sphere, not as a full sphere. Ifyou want to exaggerate the size, that's your choice, but I personally don't think its necessary.
Now, lets move on to the neck and shoulders. When you draw the shoulders, notice that they are slope down smoothly, they aren't flat. Try to take the musculature structure of the neck and shoulders into consideration, especially if you are going for a more realistic look. They should be shaped morelike a clothes hanger, and not drawn flat an hard.
Here are some more examples of various shoulder positions. Notice that the shoulders are never drawn flat and dull.
One more thing I wanted to cover regarding the torso is how to draw it if an arm is lifted. ^_^ I have personally found this difficult sometimes, so I figured it was a good thing to go over. If the arm is lifted, then the backof the torso will be exposed. Although a female's torso isn't as round and full as a males, it should still stick out in the back. Don't make the upper torso too narrow. Notice also how the top of the right-most breast doesn't just keep curving inwards in a circle; remember that it is not a full sphere, so it is attached to the muscles of the shoulder.
Next, let's move on to the arms. The armsconsist of three basic sections: the upper arm, the foream, and the hand. Each can be represented in prelimiary sketches by oval shapes. Now, I know some people don't like using the shapes; you do not have to do it this way, this is just one possible way to go about sketching arms. Some books recommend using cylinders, but it's better to use flat ovals because they more closely match the shape ofthe arm. It isn't shown here, but if the arms are held loosely at the side, the hands should come down to the middle of the thigh. The elbows should be at about waist length.
Once you have your basic shapes of the arms down, you can refine them and make them look more realistic. This is a little more difficult. ^_^ When drawing the arms, don't make them straight and flat; arms have muscles,...
