Vertical portrait based on [the reference photo], rendered in a hand-drawn colored pencil illustration style with clean line art and slightly rough pencil outlines, combined with soft watercolor wash textures. Simple facial features with dot eyes and a gentle smile, semi-cartoon realistic proportions. Visible pencil strokes layered with subtle watercolor gradients, flat yet detailed coloring, minimal shadows, and soft highlights. Bright pastel colors with vivid, natural saturation. Cozy and cheerful storybook atmosphere, children's book lifestyle sketch style, high clarity, non-photorealistic, no photo textures.
