A portrait of a woman with a neutral expression, movie poster colors. The setting should feature cool lighting with blue tones casting a subtle glow on her face. She should have smooth, clear skin and dark hair pulled back, with a few strands falling loosely around her face. The background should be a gradient of blue and purple, softly blending to enhance the cool, serene atmosphere. The woman should be wearing a simple, dark-colored top, and the overall composition should be minimalist and modern
