Nano Banana 2 プロンプト - 水墨サスケの原作準拠修復

【修复原则申明】 请在原有图片基础上进行修复，遵循以下原则： 保持核心元素不变（仰头构图、飞溅粒子、高对比光影、整体冷调插画风格） 样貌装扮按原著：黑发蓝泽、黑眸（可选写轮眼）、白衬衫+黑网眼内衬、紫色注连绳、草薙刀深色鞘 最后按原著上色：仅做 colorize（配色还原），不改变线稿、光影与整体风格 这是修复+上色，不是重绘 【第一步】样貌原著还原 提示词: Restore Sasuke's canon face: sharp black eyes with cold gaze (optionally red Sharingan with tomoe), natural healthy skin tone (not grey), black hair with dark blue sheen, long strands at the back, cool arrogant upward expression. Keep the exact same line art and shading style. 【第二步】装扮原著还原 提示词: Canon outfit (Shippuden "Hebi/Taka" era): white open shirt over BLACK mesh undershirt, PURPLE/lavender thick rope belt (shimenawa) at the waist (currently grey-blue, recolor to purple), white/light-grey hakama pants. Fix the Kusanagi sword: clear tsuba and sheath connection, recolor the sheath to dark navy/black, keep the white-black diamond wrapped hilt. 【第三步】手部解剖修复 提示词: Fix the hand resting on the sword hilt, clear fingers with distinct knuckles, natural relaxed grip, correct thumb-index connection. 【第四步】原著上色且不改风格 (Critical: Colorize Only) 提示词: COLORIZE the whole image to canon Naruto palette: warm natural skin, deep black hair with blue sheen, purple rope belt, black mesh, white shirt with cool grey shadows, dark sheath. CRITICAL: preserve the existing ink-wash line art, splatter particles, high-contrast monochrome-feel lighting and overall cold illustration style — only add canon colors, do NOT change style, composition or lighting structure.
