A striking portrayal of Harley Quinn exuding an eerie aura of anger, captured within the confines of a dimly lit cell. Her tattoos are intricately detailed as she gazes directly at the viewer, tattooed skin appearing vividly real in a highly detailed, full-length 8k photo-realistic portrait. Captured with a focus on hyperrealism under diffused soft lighting, the scene has a shallow depth of field and a sharp, cinematic focus. The image embodies a haunting allure while avoiding any technical imperfections such as blurriness, deformed anatomy, or exaggerated proportions. The overall composition maintains an unsettling yet captivating quality.
