Please use the uploaded photo as the unique character reference, strictly locking the character's facial features, face shape proportions, hairstyle, hair color, and overall identity characteristics, size 3:4. Adjust the background atmosphere to a clear, sunny, and transparent outdoor scene, with the sky in a rich vintage blue. Maintain the original hairstyle, only letting the hair strands flutter naturally in the wind. The character's eyes are bright, with a slight sense of innocence, mystery, and charm. Emphasize facial details and exquisite highlights, with an overall blue and white transparent tone. Add slight ultra-blue photographic grain, shallow depth of field, bokeh, soft light spots, cinematic feel, portrait lens f/1.8, lens flare, rainbow diffraction, and gradient halo. Add a distinct soft light filter overall to make the skin texture soft and delicate, while retaining the real skin texture. Do not change the facial proportions, face shape, hair color, or character identity.
