Serious Woman With Sci-fi Gun And Spirit Seahorse

A striking portrait of a young woman with short, dark hair with purple streaks, piercing blue eyes, and fair skin, holding a futuristic sci-fi gun over her shoulder. A luminous, ethereal seahorse-like creature made of light blue energy hovers near her hands. She wears a grey tactical jacket with a black high-collar undershirt and fingerless gloves. The background features ancient stone ruins and a muted, cloudy sky. The art style is a blend of realistic and anime, with a serious and mysterious mood. The lighting is soft and diffused, highlighting the glowing seahorse. Colors are cool tones of grey, blue, and black, with hints of orange from the gun's lights and autumnal foliage in the distance. Detailed facial features, textured clothing, and subtle depth of field.
