Gothic Lovesick Anime Schoolgirl Portrait

Anime illustration based on the character and composition of the reference image, maintaining the school uniform motif. The mood is [feverish, lovesick, slightly unhinged joy]: head tilted back slightly, eyes half-lidded, flushed cheeks, and mouth open in a breathy smile with visible teeth. Hair is wild and messy, with tangled jet-black strands falling across her face and spreading outward. She holds an aged cream envelope close to her mouth, closed with a central [red wax seal]. Dark thorny vines wrap tightly around both hands, wrists, fingers, and across the envelope in a heart-like tangle. Exactly 8 small [purple aster-like blossoms] are distributed on the vines: 2 near the upper envelope, 2 on the right side, 2 around the hands, and 2 near the wrists and lower vines. Style: Dramatic, painterly, high-detail anime illustration with deep shadows, muted skin tones, and a gothic romantic atmosphere. Background is a solid, flat vivid [red], with no extra objects, text, or watermarks.
