身穿黑色洋裝的女子凝視自己的油畫肖像

Create a scene where a stunning woman is standing in a modern art gallery, wearing a flowing black tulle dress, seen from behind with a side glance, as she looks at a large oil portrait of herself hanging on the wall. The painting should depict the same girl in a realistic and expressive oil style, showing her face and upper body. The gallery wall is clean and white, with a soft spotlight illuminating the artwork, creating a professional exhibition atmosphere.
