Do NOT change the main person: keep face, hair, body, dress, hands, cake, and everything about her exactly the same. ONLY add a large circular white projector light behind her on the wall. The projector creates a bright round white circle of light on the wall, like a spotlight or projection screen. The circle is empty and clean, pure white, clearly visible behind the person. Dark room background, warm cinematic atmosphere, soft glow around the projector circle. Do NOT add any images or patterns inside the circle. Keep the circle blank white.
