Certainly. Here's a detailed analysis of the person's observed emotional expressions based on the image:

1. **Eyes & Eyebrows**:
   - The eyebrows appear slightly raised and pulled together. This can indicate confusion, surprise, or concern.
   - The person's eyes seem a bit wide open but not excessively. This can be a sign of alertness, interest, or mild surprise. 
   - The eyelids appear slightly droopy, which might suggest tiredness or resignation.

2. **Nose & Cheeks**:
   - There's no visible scrunching of the nose or raised cheeks, which would indicate strong emotions like disgust or intense happiness respectively.

3. **Mouth & Lips**:
   - The person has a cigarette in his mouth, so the lips' position might be influenced by this external factor.
   - However, the mouth's corner is pulled slightly downward. This could indicate sadness, disappointment, or contemplation.

4. **General Face & Head Position**:
   - His face seems to be slightly tilted upward, which can be a sign of defiance, challenge, or in some contexts, pride.
   - The overall facial muscles seem a bit tense, suggesting some underlying stress or unease.

5. **Body Language** (limited visibility from the image):
   - The visible portion of his suit suggests formality or being in a serious environment. This might influence his expressions.
   - The slight lean towards the right can mean a range of things from being at ease to slightly withdrawing from a situation, but it's challenging to conclude definitively with the limited view.

6. **Genuineness of the Emotion**:
   - The combination of the droopy eyelids, slight downturn of the mouth, and raised eyebrows all converging might suggest a genuine sense of contemplation, concern, or unease. There isn’t a clear sign of insincerity, such as forced smiles (Duchenne vs. non-Duchenne smiles) or mismatched facial regions. 

Conclusions:
From the observed details, the person in the image seems to be experiencing a mix of contemplation, mild surprise or alertness, and possibly a hint of sadness or disappointment. The overall emotion appears to be genuine, given the consistency across different facial regions. The person might be in a moment of deep thought, potentially about a concerning or challenging matter. Given the context of the cigarette and the formal attire, there could be an element of stress or seeking a momentary escape from a situation.
