Based on the image provided:

1. **Eyes:** The eyes are wide open, which often suggests surprise or alertness. The eyebrows appear to be slightly raised, reinforcing this idea of surprise or astonishment. There doesn't seem to be any tension or wrinkling in the area between the eyebrows, so it's unlikely that this expression is rooted in anger or frustration.

2. **Mouth:** The lips are parted and seem to curve slightly upward, indicating a smile. However, this isn't a broad, joyous smile; it's more muted. The teeth being exposed in this manner, without the broad stretching of the cheeks, may indicate a feeling of unease or discomfort.

3. **Face Coloration:** The paleness and the blueish tint of the skin can suggest that this is either an artistic choice or some form of makeup, which could potentially be masking any natural changes in skin color due to emotional reactions. 

4. **Posture and Body Language:** The shoulders seem to be slightly raised and tense, which can indicate unease, stress, or defensiveness. The person's head is tilted slightly, often an indicator of curiosity or confusion.

5. **Genuineness of Emotion:** While there is an evident smile, the combination of the wide eyes, the not-so-broad smile, and the posture suggests that there might be mixed feelings or emotions at play. The smile might be a social signal – perhaps to indicate non-threat or friendliness – but the eyes and body language suggest surprise, unease, or even mild fear. The disparity between the mouth and the eyes can often indicate a smile that's not completely genuine, or at least mixed with other emotions.

In conclusion, the person in the image seems to be experiencing a mix of surprise and unease, possibly with an element of curiosity. The smile, while present, may not be entirely genuine, and could be an effort to convey a different emotion to the external environment than what is genuinely felt. This kind of expression can sometimes be seen when someone is caught off-guard or is processing new, unexpected information but is trying to appear calm or amicable.
