Start out with a circle. This will be the outline for the ball of the nose. Depending on the shape of the nose, the circle can be drawn wider or taller. In this case, I’ll keep it simple and use a circle.
Nostrils: From the bottom of the circle on both sides, draw two horizontal, curved lines. Then on the outsides of these lines, add vertical, curved lines, as shown below.
The bridge: To create the bridge of the nose, draw a diamond shape going vertical from the circle to where the top will split into the eyebrows. The top and bottoms of the diamond do not have to be closed.
You might also notice the altercation of the circle, which now has the left and right corners cut off. This will create the form and shape of the nose when adding in shading.
Shading: When viewing the human nose from the front, you can notice that there are no hard lines along the bridge of the nose. To maintain the soft edges, lightly shade in the plains that lie on the side of the nose. To help create contour, shade along the sides in the same angle of each plain. By doing so, the lines of the shadow will show the direction of the surface.
Now add in more shadow underneath the nose and in the nostrils while softening the lines of the bridge. Remember that inside the nostrils would be the darkest spot, and as you move out of the nostrils, the shadow will become lighter.
Continue shading. Keep in mind the source of light to include the cast shadows and highlights.
