1. **Eyes**: The eyes appear wide and alert, with the upper eyelids slightly raised. This can be indicative of surprise, concern, or fear. The pupils seem to be in their regular state (not particularly dilated or constricted), which suggests that the person might not be in an immediate state of high arousal or fear.

2. **Eyebrows**: They are slightly drawn together, which can indicate confusion or concentration. However, they are not lowered, so this doesn't necessarily signify aggression or anger.

3. **Forehead**: There are noticeable horizontal creases on the forehead, which usually come with the raising of the eyebrows. This can be a sign of surprise or worry.

4. **Nose and Cheeks**: No particular tension or change in coloration is visible, suggesting that there isn't a strong feeling of disgust or intense emotion.

5. **Mouth and Lips**: The mouth is slightly open, which can be a sign of surprise or anticipation. The lips are relaxed and not pursed or tightened, which means there's probably no anger or disgust.

6. **Jaw and Chin**: The jaw appears slightly tense, which can indicate stress or determination.

7. **General Face Shape**: The face muscles seem slightly tensed but not overly so, which suggests alertness but not necessarily aggression.

**Overall Emotion Analysis**:
The person in the picture seems to be experiencing a mixture of surprise, alertness, and potential concern or confusion. In a social context, if someone displayed this emotion, it might indicate that they've just heard or seen something unexpected, and they're trying to process or make sense of it. It's an alert and attentive state, perhaps indicating curiosity or concern, but not necessarily immediate distress or panic.
