This is human in between dark and light. We cannot see his face, his eyes or his attitude.
All we can see is a man, silent and mysterious, standing in the dark and lightened by a sparkling light, right at his eyes. Is that window of his soul which we could understand if we can enter it?
The red shirt and black cap suggest a young man.
His beard makes him look overthinking.
All the background has a black color which makes us feel lonely and cold.
