1. **Eyes**: The eyes are slightly widened and the eyebrows are raised and pulled together. This often indicates surprise, shock, or sudden realization. The eyelids do not appear to be tightly closed, so it isn't a strong shock but more of a mild surprise or realization.

2. **Mouth**: The lips are slightly parted but not tensed. This suggests that the surprise or realization isn't necessarily negative, but could be neutral or even mildly positive. There's no clear sign of distress from the mouth alone.

3. **Forehead**: The presence of vertical lines between the eyebrows is indicative of worry or confusion.

4. **Hand Placement**: One of the most noticeable elements of the image is the person's hands placed on his head. This gesture typically signals stress, frustration, disbelief, or being overwhelmed. 

5. **Genuineness of Emotion**: Given the congruence between multiple facial features and the hand gesture, the emotion displayed seems genuine. If someone was attempting to feign surprise or disbelief, we might expect to see inconsistency in their expression - for example, raised eyebrows with a relaxed or smiling mouth.

From the combined observations:

- The primary emotion conveyed appears to be a mix of **surprise** and **realization**.
- The hands on the head add a layer of **stress** or **disbelief** to the expression.
- The slight frown between the eyebrows introduces an element of **worry** or **confusion**.

Conclusively, the person seems to be having a moment of sudden realization or surprise, coupled with a bit of stress or disbelief. The emotion does appear genuine given the consistency across different parts of the face and the body language. There's no clear indication of the person trying to convey a different emotion than what they're actually feeling.
