@christinamontoya in her late 20s looking directly into the lens with a piercing, soulful gaze. She has a deep, contemplative expression that conveys a complex inner world. She wears a minimalist dark charcoal high-neck sweater and small gold hoop earrings. The lighting is cinematic Rembrandt style, with a soft light source from the side highlighting the textures of her skin and the reflection in her eyes, while the other side of her face fades into elegant shadow. The background is a soft-focus, dim library with dark wood tones. Her expression is still and quiet, but her eyes suggest she is lost in deep thought. 8k resolution, photorealistic, highly detailed iris, emotional depth, 24mm lens aesthetic.
