我读代码习惯抠每一行逻辑，玩水墨也忍不住盯着每一笔走向看。这张画石缝里探出的一株兰，重点全在叶子——要那种一笔拉出去、中途换锋、末端收得利落的流动感，石头反而只是配角，稳住画面重心就行。
提示词按笔法逻辑补全，把叶子的动势写清楚：
orchid growing from a rocky crevice, Chinese literati ink painting (wenren-hua),
elegant curved leaves rendered in single flowing brushstrokes, varied brush pressure, sharp tapered leaf tips,
a few slender blades crossing in graceful arcs, sparse ink-wash rock at the base as anchor,
plenty of negative space, subtle gradient of ink tones, calligraphic energy
叶尖那句sharp tapered最关键，不写它模型容易把叶子收成圆头，一下就没了书法气。
