Person in red jacket in ice tunnel

A lone person in a red jacket walks through a vast smooth tunnel shaped like a flowing ice cavern, with deep shadows filling the upper space. A large oval opening ahead emits a bright cool white glow, flooding the tunnel with soft blue light that transitions into darker tones as it moves outward. The ground is gently textured with faint tracks leading toward the illuminated exit. The figure appears small against the sweeping curved walls, enhancing the sense of scale and solitude. The atmosphere is quiet, cold, and minimal, with the glowing opening acting as the central focal point while the surrounding darkness remains clean and uncluttered for a cinematic wallpaper composition.
