Casual selfie in a wood-paneled elevator or small room

This is a portrait photograph of a young man taking a selfie in what appears to be an elevator or a small room with wood-paneled walls. The man is wearing a light green t-shirt, dark pants, and a dark baseball cap which he is adjusting with his left hand. He has a dark bag slung across his body. The wood-paneled walls are covered in graffiti and some posters. The lighting suggests it could be daytime, possibly indoors with artificial light. The man's expression is neutral. There is a lot of text visible in the graffiti and posters, primarily in Cyrillic script, but it is difficult to read clearly.
