A photo-realistic rendering of a large, modern lecture hall with a minimalist design. the image is taken from a bird's eye view, looking down on the empty auditorium with rows of beige chairs facing the stage. on the middle of the image, a man stands confidently in front of the stage, wearing a black suit. he appears to be in his late twenties, with a serious expression on his face. the auditorium has a wooden paneled wall, a wooden ceiling with recessed lighting, and white columns supporting the structure. the stage is empty, with no people present, and there are no other objects or decorations in sight. the overall atmosphere of the lecture hall is one of calmness and serenity.
