篝火化作星河的宇宙奇遇

超现实、电影感的概念艺术插画：在没有可见环境的漆黑宇宙虚空中，采用高角度全景构图，两个人物被中央篝火对称分隔。左侧是一名坐在粗糙灰色岩石上的宇航员，穿高度精细的白色宇航服并戴着反光面罩，手持木棍在火上烤棉花糖；右侧是一名成年男子坐在金属折叠椅上，身体略微前倾，深色头发，穿红黑格子法兰绒衬衫、蓝色牛仔裤和棕色靴子，向篝火伸手取暖。中央篝火的火焰无缝变成照片级写实的螺旋星系，星光、宇宙尘埃和旋转运动向上拱成天体华盖。篝火提供温暖橙色主光，星系提供冷蓝紫色次光，柔和而深邃的阴影强调对比；黑、橙、蓝、紫为主色，白、红、棕为点缀。锐利焦点、超细节纹理、高动态范围、空灵而温暖的氛围，不含文字或品牌。

【English Prompt】
Surreal cinematic conceptual art illustration in an abstract cosmic void with no visible environment. Use a high-angle full shot with symmetrical balance, separating two characters by a central campfire. On the left, an astronaut sits on a rough gray rock in a highly detailed white spacesuit with a reflective visor, holding a stick to roast a marshmallow over the fire. On the right, a generic adult man sits on a metal folding chair and leans slightly forward to warm his hands; he has dark hair and wears a red-and-black plaid flannel shirt, blue jeans, and brown boots. The campfire flames transition seamlessly into a photoreal spiral galaxy, with glittering stars, cosmic dust, and swirling motion arching overhead as a celestial canopy. Warm orange firelight is the primary source, balanced by cool blue and purple galaxy light; soft but deep shadows emphasize contrast. Dominant black, orange, blue, and purple palette with white, red, and brown accents. Sharp focus, ultra-detailed textures, high dynamic range, ethereal warm mood, no visible text or brands.
