Portrait pastel anime de fleurs de cerisier

Create a dreamy widescreen anime illustration in a soft pastel palette, showing a close-up portrait of a young girl with {argument name="hair color" default="silvery white with pale pink and lavender highlights"} long flowing hair, loose twin-tail-like locks, and delicate strands blowing across the frame. The scene is filled with {argument name="flower type" default="cherry blossoms"}: count 2 visible blossom branches crossing the upper left and upper right background, with many glowing petals drifting through the foreground and background. Use strong backlighting from the upper right, pearly bloom, lens flare, bokeh sparkles, translucent ribbons of light, and a shallow depth of field for an ethereal spring atmosphere. The composition is an intimate over-the-shoulder or three-quarter close-up, with the girl’s face mostly hidden by exactly 1 large opaque square overlay centered on the image, colored {argument name="overlay color" default="muted pastel pink"}, covering the facial features from forehead to chin. Add hints of a pale blue-white school-uniform-style collar and soft pink accent near the lower center. Render in high-detail modern anime key visual style, luminous painterly shading, delicate linework, cinematic lighting, romantic and serene mood, 16:9 aspect ratio.
