Use the person from the reference image. Create a photorealistic vertical portrait (9:16) of a child sitting on a wooden windowsill inside a log house. Subject: a boy seated in three-quarter view, with his head slightly tilted toward his right shoulder, looking directly into the camera. Appearance: hair matching the reference, with distinct individual strands, open expression, a soft sincere smile with a slight squint that conveys joy. Wardrobe: a linen kosovorotka in ecru (#F5F5DC) with detailed red embroidery (#B22222) on the collar, placket, and cuffs, tied with a woven ornamental belt with tassels; blue sharovary (#4682B4) tucked into white onuchi with crisscross wrapping; woven bast shoes made of linden bark (#D2B48C). Action & Pose: he holds a round woven willow basket filled with a stack of golden pancakes (#EEDC82), topped with a cluster of bright scarlet viburnum berries (#FF0000). Setting: rustic log cabin interior, lace curtains, and a clay jug with sunflowers (#FFD700) in the background. Lighting: natural side window light from the left, Rembrandt lighting, with soft shadow transitions across the face, emphasizing skin microtexture and the texture of the log walls. Framing & Composition: linear perspective, camera positioned at the child’s eye level. Camera & Optics: full-frame camera, 35mm lens, f/1.8, shallow depth of field with soft bokeh, ISO 100, shutter speed 1/200s, warm white balance 5500K. Color Palette: rich warm tones of ochre (#CC7722), terracotta (#E2725B), and wood shades (#8B4513). Details & Texture: maximum sharpness in the foreground, visible linen fibers, skin pores, droplets of juice on the berries, and the weave of the basket; deep but detailed shadows, pinpoint highlights on the berries and in the eyes. Preserve: keep the facial features and hairstyle from the reference image.
