Dual-Panel Portrait Poster: Photo & Sketch

Goal: Create a vertical 3:4 dual-panel poster featuring {argument name="subject description" default="a young woman with long wavy brown hair, wearing an orange knit beret adorned with small yellow flowers and a yellow sweater, holding a branch of osmanthus flowers near her face"}.

Layout: The canvas is split strictly 1:1 horizontally into two equal sections (top and bottom).

Top Section (Photorealistic): A high-quality studio portrait of the subject. She has soft, warm lighting, rosy cheeks, and a gentle expression. She wears dangling earrings and holds a small wooden stand with a white rabbit figurine and a mooncake. The background is a solid, soft lavender-grey. Apply a premium, warm color grade to enhance the cozy autumn atmosphere.

Bottom Section (Artistic Sketch): A black-and-white pencil or charcoal sketch illustration of the exact same pose and composition as the top image. The style should be hand-drawn with visible texture strokes on cream-colored paper. 

Text Content: Overlay text in the upper-left area of the bottom sketch section:
- "No.01" in a small, clean sans-serif font.
- "{argument name="main title" default="Warm Season"}" in a large, elegant handwritten script font.
- "{argument name="subtitle" default="Bloom in quiet."}" in a small serif font below the main title.

Visual Style: Contrast between the vibrant, realistic photography above and the nostalgic, monochrome artistic rendering below.
