Question: What's the emotion of the face?

<think>Analyzing the face reveals several critical Action Units indicative of sadness. The inner brow raiser (AU1) contributes to a downward expression of the eyebrows, enhancing the impression of distress. The brow lowerer (AU4) signals a serious demeanor, while the cheek raisers (AU6) may indicate a slight upward turn of the mouth, albeit not reaching a smile. Additionally, the lid tightener (AU7) suggests tension around the eyes, which is commonly associated with sadness. The nose wrinkler (AU9) reflects a withdrawing emotional state, reinforcing feelings of sorrow. Lastly, the chin raiser (AU17) can create a drooping effect that aligns with the overall expression of sadness. Collectively, these AUs frame the face in a way that strongly conveys sadness.</think>
