Create an extraordinary portrait of the attached person standing in an enormous underground palace buried beneath a desert. The ceiling and walls are carved from smooth pale sandstone, with a huge circular opening overhead revealing a tiny slice of desert sky far above.

Dress the person in sophisticated monochromatic ivory tailoring with a long flowing coat. Position them at the center of an enormous chamber, facing three-quarters toward camera with face clearly visible.

Use a 50mm lens at f/3.5 from slightly below eye level. Warm sunlight enters through the opening and travels down into the chamber, while soft reflected light from the sandstone illuminates the subject.

Preserve realistic stone texture, tiny grains of sand, architectural scale, fabric weight, skin pores, hair, shadows and atmospheric dust.

The chamber should feel like a lost civilization designed by a contemporary architect. Majestic but restrained.
