Create a minimalist portrait of a woman, emphasizing simplicity and clean lines. The portrait should feature a neutral, monochromatic background to keep the focus on the subject. Use soft, natural lighting to gently highlight her features. The composition should be straightforward, with ample negative space to convey a sense of calm and serenity. The subject's expression should be subtle yet captivating, conveying emotion without the need for elaborate details. The overall look should be modern and elegant, capturing the essence of minimalism in portrait photography.
