In colloquial speech, under the shoulder is usually the distance from the neck to the shoulder joint. However, the more accurate meaning of the term implies the section of the arm from this joint to the elbow. It is surrounded by a lot of muscles. If you want to learn how to represent a person realistically, study and sketch this part of the body.

Draw the axes on which the drawing will be built. The segments can be used to symbolize the bones of the arm, around which you need to draw a shape. Using sight, measure the proportional ratio of all parts of the arm and torso, record the results in the figure.
Draw the outlines of the left hand with rough outlines. The thickness of the arm at the base of the shoulder is half the length of the humerus. The arm gradually narrows towards the elbow.
Divide the length of the arm to the elbow in half. The upper half is occupied by the deltoid muscle. It is clearly visible in the photograph. Draw its shape like a triangle. Make the upper part of the muscle more convex - it should protrude beyond the shoulder joint and, as it were, cover it.
Step back from the apex of the triangle by about a quarter of its length. Here the biceps brachii is located with an overlap. Since it is not tense, the hand in this place has a smooth, rounded shape. The triceps muscle on the lower side of the arm looks the same. Draw it slightly more convex at the base.
To convey the volume of an object, shade it or fill it with paints. Softer outlines and smoother color transitions will be obtained if you choose watercolor or acrylic. Mix in the palette shades of sepia, red, yellow, brick in such proportions to get the color of the skin. Make several "batches" of mixed colors of different weights. First, paint over the lightest areas - near the elbow and along the left side of the deltoid muscle.
Fill in the lower shoulder with a more saturated shade. As you get closer to the boundaries of the muscle, the shadow should gradually become darker. Apply semi-circular strokes of dark brown near the elbow. Add some gray to the center of the deltoid. Draw the darkest, almost blackest shadow at its base on the shoulder joint.
