炭筆把舊水壺畫得沉下來

A single old metal kettle on a cloth, expressive charcoal drawing on visibly toothy warm paper. Deep compressed blacks under the body, lifted eraser highlights on the curved shoulder, confident loose contour, broad quiet background, realistic handle and spout geometry. Square 1:1 standalone finished image. No text, logos, watermark, border, multi-panel layout or contact sheet.

一隻舊金屬水壺放在布上，畫成暖色粗紋紙上的表現性炭筆素描。壺身下方壓實深黑，弧肩處用橡皮提亮，外輪廓松而果斷，背景大塊安靜，提樑與壺嘴結構真實。 方形1:1獨立完整成圖。不要文字、標誌、水印、邊框、多格排版或聯絡表。
