Photorealistic Alien in a Portal Chamber

Ultra-photorealistic render of an alien in a portal chamber. A sleek, humanoid alien with smooth iridescent skin that shifts from teal to violet stands in the center of a circular chamber. The floor is polished black basalt that mirrors luminescent rings of several portal frames embedded in the walls. Floating around are looping portal rings with surfaces swirling nebula colors and faint starfields. The walls are lined with carbon-fiber panels and glowing blue conduits; large arched portals display rolling cosmic vortices. The atmosphere is cool and moody, with blue and teal lighting, a soft amber glow from certain portals, and fine particles drifting in the air. The alien has large almond-shaped eyes, delicate facial features, subtle cranial ridges, and elongated fingers. It wears a minimal, high-tech suit with matte and brushed-metal textures. The camera angle is slightly low to emphasize the alien’s presence, with depth of field that blurs the far portals into a dreamy bokeh. Render with photorealistic textures, subsurface scattering for the skin, realistic reflections, and micro-detail on the suit and chamber surfaces.
