crowd of people in what appears to be an indoor sports arena. The crowd is gathered on the ground floor and in the stands. There is a large orange banner hanging above the stands. The arena has a high ceiling with exposed metal beams. The lighting is a mix of natural light and artificial lights. Some people are walking around, while others are standing and watching something out of frame. There is a sense of anticipation or excitement in the air. The sound of a horn or similar instrument can be heard. Some individuals are visible in detail, including one wearing a blue jacket and another with glasses and a black hoodie.
