"Create a realistic image of Semyon Mogilevich, the notorious Russian mob boss, in a prison cell. The scene should show Mogilevich sitting on a prison bed, wearing an inmate uniform. The cell should be austere, with concrete walls, a small window with bars, and typical prison elements like a metal toilet and a basic sink. Mogilevich should have a serious and contemplative expression, adding to the dark and ominous atmosphere of the scene."
