To keep the size of the ear

To answer your question, I will go through each option and explain how it relates to maintaining proper proportions while painting a portrait of a face.

1. Keep the size of the ear: It is important to maintain the relative size and position of the ear when painting a portrait. This helps ensure that the ear is not too small or too large compared to the rest of the face. So, keeping the size of the ear is an important aspect of maintaining proper proportions.

2. Keep the corners of the mouth: The corners of the mouth play a significant role in the overall expression of the face. By accurately depicting the corners of the mouth, you can capture the specific emotions of the subject. Therefore, it is important to keep the corners of the mouth to maintain proper proportions and convey the intended expression.

3. Keep the width of the nose: The nose is a prominent feature of the face, and its width has a direct impact on the overall balance and symmetry of the portrait. By accurately portraying the width of the nose, you ensure that it is in proportion to the other facial features and maintain a realistic representation.

4. Keep the location of the eyes: The eyes are often considered the focal point of a portrait. Their correct placement is crucial for capturing likeness and achieving accurate proportions. By keeping the location of the eyes, you ensure that they are correctly positioned on the face, maintaining the likeness and proportionality of the portrait.

Based on the explanations above, the correct answer is: "To keep the width of the nose." This is because maintaining the width of the nose is indeed an important aspect of maintaining proper proportions when painting a portrait.
