GPT Image提示词：

A towering mechanical praying mantis stands motionless in a rain-slick futuristic alley, its elegant insect silhouette built from layered jade-green armor plates, brushed steel joints, and fine exposed cables. Its angular head tilts slightly toward the viewer, with two small amber sensor lights glowing beneath a ridged brow. Long folded forelimbs rest close to its chest, their edges precise and tool-like rather than threatening. Wet pavement mirrors narrow bands of cyan signage and distant orange window light; steam drifts from a street vent, while compact buildings recede into soft atmospheric blur. Frame the machine in a vertical three-quarter portrait from a low camera position, keeping its head and upper limbs sharply defined against the alley depth. Cinematic science-fiction concept illustration, tactile materials, moody contrast, restrained teal, jade, and amber palette, subtle volumetric mist, intricate engineering, polished high-detail finish.

中文提示词：

一台高大的机械螳螂静立在雨后未来巷道中，优雅的昆虫轮廓由层叠翡翠绿装甲、拉丝钢关节与细密外露线缆构成。棱角分明的头部微微转向观者，脊状眉甲下方亮着两点琥珀色传感灯。修长前肢收拢在胸前，边缘精确如精密工具，并不显露攻击姿态。湿润路面映出青色灯牌与远处橙色窗光，街边排气口升起蒸汽，紧凑建筑向景深处渐渐虚化。采用竖幅三分之四肖像构图与低机位，让头部和前肢清晰突出。电影感科幻概念插画，材质触感丰富，明暗沉静对比，青绿与琥珀色克制搭配，薄雾柔和，机械细节精密。

说明：昆虫机甲以静立姿态成为雨巷焦点，反光街面增强未来都市氛围。
