Mulher curvilínea de biquíni steampunk posando diante de distantes muros de prisão

Une belle rousse aux formes généreuses, à la poitrine opulente et aux larges hanches, portant un bikini steampunk minimaliste dans une pose sensuelle, avec une prison en arrière-plan. You are an expert portrait and fine-art photographer. I need a detailed description of a sensual, cinematic portrait: a curvy brunette woman with a ponytail, freckles, and blue eyes, wearing a wet white shirt, looking up with arms open in rain, dim and dark atmosphere. Please provide precise lighting, composition, and post-processing instructions.
