Create an image of a serene and realistic scene featuring a black girl practicing yoga. Capture a back camera view of her as she performs a yoga pose on a small, white mat. She is dressed in a sleek, black yoga outfit. The setting is an old, large room with an antique charm, characterized by its high ceilings and expansive window openings. The room is bathed in the warm, golden hues of a sunset, with sun rays streaming through the large windows, casting elongated shadows on the wooden floor. Ensure the overall atmosphere is tranquil and reflective, highlighting the interplay of light and shadow in the spacious, vintage interior.
