Sacred Geometry Halo Portrait

Use the exact same face from the reference image and Ultra realistic close-up studio portrait headshot of an {argument name="subject" default="American white man"} with sharp jawline and defined facial features, dark hair, intense eyes. Shot from mid-chest up. Background Element: a perfect glowing circle of {argument name="halo color" default="warm golden-white"} light positioned precisely behind his head like a sacred halo — the circle is made of soft continuous light tube, glowing from within, creating a luminous ring that perfectly frames his face and head. The circle casts a warm golden glow onto the background and subtly wraps around his cheekbones and jaw. Face lit with large octabox from slightly above-left creating warm skin tones with sharp facial definition. His silhouette perfectly centered within the glowing circle. Wearing a {argument name="clothing" default="black turtleneck"}. Background: deep matte black seamless with only the glowing circle visible. Expression: direct commanding gaze, quiet authority. Sacred, cinematic, powerful. "OzairAI" faintly engraved at the bottom of the circle like a studio signature. Vertical 9:13 format. Ultra photorealistic, 8K, no text overlays, cinematic color grading.
