A full-body caricature portrait with proportional composition from feet to head, featuring extremely exaggerated facial and head features—eyes, nose, and lips are enlarged and distorted. Style: textured paper texture, retaining original charcoal structure and strong brush/pencil strokes, emphasizing aesthetic composition and expression. Pure black color palette, focusing on brushstroke effects. Specific style: pencil brush strokes, no text elements, stylized positioning near the shoulders for aesthetic replacement, avoiding the bottom-right area. Output: a big-head caricature with noticeably exaggerated head size for comic effect, while maintaining charcoal and brush stroke style.
