We have had a look at the eyes and nose, the mouth and ears are next. Of course, they also come in different shapes and sizes.
Look at the line where the lips meet, is it straight or curved? Does it curve up, down or both? Draw the curves and basic shape in lightly. Notice the difference between the top and bottom lip, is one fuller?
The middle line where the lips meet is the darkest, the outline of the lips is more a change of colour than a distinctly drawn line. The lip edges should be kept soft. Draw in any other features you notice on the lips and around the mouth eg. lines, dimples or moles.
When drawing ears the tops are generally in line with the eyes and the bottom is between the nose and mouth. Look at the ear lobes are they free or attached, do the ears sit flat or stand out?
Profile
A profile drawing begins with a circle, divide it through the centre with a verticle and a horizontal line. Shorten the curve at right, lower section of the circle. Draw in the neck looking at the lines and the way the neck curves.
The eye is on the horizontal line, about one third of the way along the left side of the circle, a sideways V. The top of the ear curves just above the horizontal line right at the centre. Draw in the hairline, the chin and the nose fill in with shading.
Have a Great Day.
