several individuals on a tennis court at night

several individuals on a tennis court at night. The court is blue with green sidelines. There's a standard tennis net separating the halves. A light pole illuminates the court. Behind the court, there's a black fence with white rectangles on it. One person, wearing a pink top and patterned leggings, is actively hitting tennis balls. Another person is wearing blue pants and a white top. Three other people, dressed in more casual clothing, stand near a wire basket filled with tennis balls, presumably coaching. They offer instructions and feedback after each shot. One coach is wearing a grey sweatshirt, one is wearing a white sweatshirt, and the third is partially obscured. Tennis rackets are visible near the basket.
