A photorealistic, highly detailed, cinematic portrait of an **ethereal young woman** (around 25 years old) with a **regal expression and intensely focused eyes**. She has long, luxurious, jet-black hair that flows slightly over her shoulders. She is dressed in an opulent, heavy **traditional black gown** layered with intricate, **raised gold filigree and embroidery** across the bodice and sleeves.

**Composition:** She is positioned centrally, her hand gently resting on the braided bridle of a magnificent, muscular **purebred black Arabian horse**. The horse's coat is gleaming, contrasting sharply with the environment.

**Setting and Atmosphere:** The scene is set in a vast, empty **sand desert or arid plain** during the **'Golden Hour' sunset**. The sky is a blend of deep burnt orange, soft rose, and fading indigo.

**Lighting and Photography:** **Dramatic, low-key cinematic lighting** with a strong rim light defining the horse and the woman's profile. **Soft volumetric light** (dust motes visible in the air). Shot on a **wide-angle lens** (e.g., 24mm) with a **shallow depth of field** ($f/1.8$), focusing sharply on her eyes. **Ultra quality, 16k, Octane Render, ZBrush, hyper-realistic texture detail.**
