Use the uploaded portrait as a character/face reference. Keep the character's recognizable facial features and natural facial proportions, including eyes, eyebrows, nose, lips, face shape, and skin tone. Naturally blend the face into the illustration style, rather than making it photorealistic. The hairstyle should also reference the original photo, but be naturally adjusted according to the illustration character. Generate a full-body, vintage European storybook-style fantasy illustration: a character stands alone in the center of a tranquil birch forest. The character is slightly facing the viewer, with a calm and gentle expression and a relaxed, natural posture. She is wearing a loose, warm beige/cream chunky knit turtleneck sweater with a very high ribbed collar. The sweater has extremely delicate chunky knit patterns, including longitudinally extending cable knit patterns. The sleeves are long and loose, with ribbed cuffs. Her lower body is adorned with a long, flowing beige/cream vintage skirt, knee-length approaching the ankles, with delicate botanical embroidery and intricate lace-like floral details around the hem. She is wearing patterned knit socks and dark brown vintage lace-up ankle boots with slightly upturned pointed toes and fine leather textures. A small robin naturally perches directly on top of her head, nestled in her hair. This bird must be clearly visible and small in proportion. Its chest is warm orange-red, wings are brown, and its beak is small and natural. In the lower right corner of the picture, a second robin stands naturally in the vegetation on the ground. This bird also needs to be clearly visible, with orange-red breast feathers, brownish-gray wings, distinct feather details, and a natural posture. The character is surrounded by a dense, tranquil birch forest. The background includes many tall, slender white birch trees with iconic dark tree markings and fine branches extending upwards. Multiple layers of birch trees in the background softly fade into the distance. The forest floor is covered with small wildflowers, delicate white blossoms, green and brown vegetation, grasses, fallen leaves, moss, and tiny woodland plants. On the left side of the picture, a narrow, gently curving stream flows through the forest, with small stones and moss-covered rocks along its banks. The stream naturally extends into the deep background. The overall atmosphere is quiet, fantastical, and nostalgic, with soft, subdued sunlight filtering through the trees. The color palette is restrained: warm beige, cream, soft greens, pale blue-grays, browns, and gentle orange accents. Art style: extremely detailed hand-drawn vintage storybook illustration, fine ink lines, delicate pencil strokes, intricate cross-hatching, subtle watercolor and colored pencil shading, visible handmade paper texture, precise botanical depiction, meticulous fabric and knit textures, softly diffused background, slightly imperfect traditional hand-drawn feel, nostalgic European fairy tale book aesthetic. The face must be seamlessly integrated into the illustration. Do not make the face too sharp, shiny, smooth, or photorealistic. Maintain the same softness, lines, hatching, and watercolor texture as the rest of the image. The hair should also have an illustrated pencil/ink line texture, rather than looking like a pasted-on photo hairstyle. Maintain a full-body vertical composition, similar to the reference scene: the girl is centered, her head near the upper middle of the frame, her feet fully visible at the bottom, the robin clearly perched on her head, the second bird clearly visible in the lower right, and the stream clearly visible on the left. Do not add any text, letters, logos, watermarks, borders, embedded reference photos, other people, other animals, modern objects, modern clothing, or photographic elements. Do not unnecessarily alter the forest composition. Maintain the entire picture as a unified piece of traditional illustration art.
