Image description

The image shows the face of a person who expresses the emotion called interest. This emotional state is reflected on the outside, through different facial expressions. There are forty two individual muscles in the face, that are activated by the respective emotion, and impacts facial expressions on the facial elements: forehead, eyebrows, eyelids, nose, cheeks, lips, chin.

The face is oval, rendered blank, outlined, with a broad forehead and a square jaw. The wide ears, on either side of the edge of the face, are rendered as two vertically elongated ovals, marking the earlobe. The nose, in the center of the face, is long and ends at the base, above the lips, with a convex or curvy tip with wide nostrils, on either side.

The eyebrows, under the forehead and above the eyes, are rendered as two embossed, slightly sloping lines, highly arched on the edges, towards the temples on each side of the face. The eyes are shown as two blank horizontal ovals, very flattened, in the center of which is the eyeball highlighted by a thickened circle.

The mouth under the nose is closed, with the lips sealed together and plumpy, the lower one, being rendered blank, and the upper one highlighted embossed.

The hair on the head is cut short, starting from the border of the forehead, and on either side it frames the face above the ears, left and right, and is fully embossed.

In the case of interest, the eyes are very large, wide open. The eyebrows are very high above the eyelids, at the forehead, and arched, denoting attention and curiosity. Raising the eyebrows very high folds the skin above them into a crease, marked just above the sharp corners of the eyebrows through a dashed line, curved upwards. Another wrinkle formed on the forehead is highlighted by a dashed line, curved upwards, located on the central point between the eyebrows. This crease occurs when the eyebrows get closer to each other, as in a frown, and bulge the skin between them.
