Eye Shape and Size: Make sure to specify that the beautiful teenage girl has proportionate, realistic, and attractive eyes. You can describe them as "big and expressive blue eyes" and ensure they are proportional to the rest of her face.

Symmetry and Alignment: Specify that the eyes are well-aligned and symmetrical to look natural and harmonious in the girl's face, avoiding any visual distortions.

Realistic Details: Include realistic details in the eyes, such as the pupil, iris, and sclera (white part of the eye). Carefully represented details will enhance the overall appearance of the eyes.

Proper Lighting: Specify the direction and intensity of the light to properly reflect on the eyes, giving them a realistic shine.

Avoid Exaggerations: Refrain from describing the eyes with exaggerated or unrealistic features, such as overly large sizes or overly bright colors.

Use References: If possible, provide visual references or images that illustrate how you would like the eyes to look.
