Make “Portrait to Concept-Art Sketch Sheet” yours

Turn the uploaded portrait into a character-design sketch sheet inspired by professional cartoon concept art. Keep the girl's exact hairstyle, cardigan, black turtleneck, layered necklaces, hoop earrings, and overall facial identity recognizable. Place the original colored portrait on the left and create three hand-drawn pencil caricature versions around it on a clean white background. Use loose sketch lines, expressive oversized eyes, simplified facial features, soft graphite shading, and charming animated proportions. Maintain the warm, friendly personality of the subject while exaggerating facial expressions slightly. High-quality concept-art sketchbook style, character exploration sheet, clean composition, monochrome pencil drawings with realistic sketch texture.
