Generate Ash And Oil Warrior Portraits

A raw, intense portrait of a tribal warrior. Their face is covered in a base of dry, matte grey ash (powder texture). Over the ash, thick, vertical lines of black viscous oil have been drawn down the eyes and cheeks. The oil is cutting through the ash, turning it into a dark sludge where they mix. Beads of sweat are breaking through the ash on the forehead. The eyes are piercing and clear. Technical Specs: Captured with a Phase One IQ4 150MP, 150mm Telephoto lens at f/5.6. Lighting is a single hard source (sun) creating high contrast. Real fluid dynamics: the oil has high viscosity and surface tension, refusing to mix instantly with the dry ash. Skin texture is gritty and hyper-detailed. 8K resolution, raw optical realism, monochrome or desaturated color grading.
