The individual in the image displays several distinct facial features that suggest specific emotions or states of mind:

1. **Eyes**: The eyes are wide open with raised eyebrows. This often signifies surprise, shock, or alarm. The white parts of the eyes (sclera) are prominently visible above and below the iris, which reinforces this sense of heightened alertness or surprise. The direct gaze also indicates engagement or focus on something or someone.

2. **Mouth**: The mouth is slightly open, which could be an indicator of astonishment or being taken aback. The downturned corners of the mouth might indicate a touch of displeasure or discomfort.

3. **Facial Muscles**: The tautness of the facial muscles, especially in the forehead and around the eyes, indicates heightened arousal or alertness.

4. **Nose**: The flaring of the nostrils can be a sign of heightened arousal, potentially due to excitement, anger, or fear.

5. **Facial Hair**: The facial hair itself doesn't convey emotion, but its arrangement can influence our reading of the face. The mustache's downturned edges might amplify the appearance of the downturned mouth, making the face appear more displeased or skeptical.

Given these observations, the primary emotion conveyed seems to be one of surprise or astonishment, potentially mixed with a hint of displeasure or skepticism. There's a strong sense of engagement or focus, as though the person has just witnessed something unexpected.

Regarding genuineness: The intensity of the wide eyes and the engagement of multiple facial muscles suggest that the emotion is genuine. However, the slightly exaggerated nature of the expressions (very wide eyes, prominently downturned mouth) might indicate that the individual is emphasizing or amplifying their reaction for effect, potentially for comedic or dramatic purposes.
