Create a perfectly centered split-composition portrait of the uploaded young man, combining two artistic styles in one image. The left half of the image should be a highly realistic photograph, preserving the subject’s exact facial structure, curly hair texture, skin tone, glasses, and expression from the uploaded reference image. He is wearing a soft light blue hoodie with realistic fabric folds and natural lighting. The right half of the image should transform seamlessly into a highly detailed black-and-white doodle sketch version of the same person, while still maintaining recognizable facial proportions and hairstyle. The sketch side should feature hand-drawn pencil and ink textures, stylized shading, playful doodle aesthetics, and artistic linework. The transition between both halves must be perfectly aligned down the center of the face and body, creating a clean and visually striking split effect. The background should resemble lined school notebook paper filled with black-and-white doodles such as: — Hearts — Stars — Arrows — Clouds — Smiley faces — Tiny icons — Handwritten Korean Hangul text: “[Your Text]” The doodles should feel playful, youthful, and naturally hand-drawn across the paper surface. Lighting on the realistic side should be soft and cinematic, while the sketch side should have high-detail illustrated shading and ink textures. The overall composition should feel modern, creative, trendy, and social-media aesthetic. Ultra-detailed textures, photorealistic realism on one side, high-quality digital doodle illustration on the other, seamless artistic blend, centered composition, premium digital art quality. Vertical portrait format, ultra-HD resolution, realistic depth, clean aesthetic, highly detailed finish.
