(masterpiece, best quality, 8k, ultra-detailed, photorealistic, professional photography), medium shot portrait of a stunningly beautiful young woman with long, flowing auburn hair and piercingly bright blue eyes. She has fair, flawless skin and full, soft pink lips. She looks directly into the camera with a captivating, neutral expression. She is completely topless, exposing her large, full, and perfectly round bare breasts. Her prominent, erect nipples are pierced with thick silver captive bead rings. A heavy, black leather collar with silver studs is clasped tightly around her neck, featuring a silver D-ring at the front. A silver metal chain is attached to the collar's D-ring, leading down and connecting to the piercing on her left nipple. Another chain connects her left and right nipple rings, draping between her breasts. The background is a simple, textured, dark gray concrete wall. The lighting is soft studio lighting, creating subtle shadows that accentuate her features and the curves of her naked torso., <lora:add-detail-xl:1.2>, <lora:attractive_notrigger:1.2>, <lora:detailed_notrigger:1.2>, <lora:LCMTurboMix_Euler_A_fix:1.2>
