### Facial Expressions:
1. **Eyes:** The eyes are slightly widened, with the eyebrows drawn together and slightly raised. This can indicate a state of alertness or surprise. The glasses might hide some of the finer details, but there's visible tension in the upper eyelids and forehead, which often corresponds to stress or concern.
 
2. **Mouth:** The lips are slightly parted and appear to be tense, which can indicate a momentary intake of breath, possibly due to sudden realization or surprise. The downturned corners of the mouth suggest sadness or concern.

3. **Nose:** The wrinkles on the bridge of the nose, coupled with the furrowed brow, can indicate a combination of confusion, concentration, or distress.

4. **Skin:** The complexion appears somewhat pale, which can be indicative of shock, fear, or distress. However, external factors like lighting and temperature can also influence skin tone.

### Body Language:
1. **Posture:** The slight forward lean suggests engagement or focus on something of interest or concern. This posture is often adopted when someone is trying to perceive something more clearly, either visually or audibly.
 
2. **Clothing:** The zipped-up jacket and scarf indicate that it's cold, which can affect body language interpretations. Cold environments can lead to tensed muscles and hunched postures.

### Potential Emotions Displayed:
- **Primary:** The most prominent emotion seems to be concern or distress. This is inferred from the combination of the widened eyes, furrowed brows, and slightly open mouth.
  
- **Secondary:** There's an underlying hint of surprise or shock. The tension around the eyes and the posture suggest that he might have witnessed or heard something unexpected.

### Conclusion:
The individual in the picture appears to be genuinely experiencing feelings of concern, distress, and possibly surprise. The environment, especially the forested background and the cold-weather attire, may suggest that he's in an unfamiliar or unexpected situation, further supporting the interpretation of surprise and concern. The facial expressions and body language cohesively tell a story of someone who is in a heightened state of alertness, potentially due to an unforeseen event or revelation.
