RetroSci style. A space marine stands tall in his bulky armor, dark and battle-worn, as he gazes into the eyes of an elegant alien woman with vibrant, shimmering skin. Her long, flowing hair glows faintly in the low light of the alien moons above. They stand in an abandoned alien city, with crumbling stone structures covered in strange alien vines.

The sky is dark purple, with distant nebulae swirling in vibrant hues of pink and blue, casting a romantic glow over the scene.
