Photoreal Alien in the Roman Forum

Ultra-photorealistic depiction of a humanoid alien in ancient Rome, standing in the crowded Roman Forum under a bright Mediterranean sun. The alien has pale blue-gray skin, a smooth dome-shaped head with no hair, large dark almond eyes, and subtle bioluminescent markings along the temples. It wears a tailored, performance-ready version of a Roman tunic with leather sandals adapted to its digits, and a simple cloak fastened with a metallic clasp. In the background, marble columns, arches, statues, and a stone fountain; citizens in togas mingle, including a centurion in lorica segmentata who glances with curiosity. Chariots travel along a sunlit street; vendors, philosophers, and students fill the scene. The alien holds a small tablet-like device projecting faint holographic glyphs that shimmer over the tunic and stones, hinting at its interstellar origin. Realistic textures: weathered marble, dusty air, woven fabrics, skin pores, reflected light, and natural shadows. Depth of field softly blurs the far background to emphasize the encounter.
