Emerald Aurora over Silent Forest River

An ethereal night landscape: emerald aurora borealis ribbons swirl across a dark velvet sky above a serene forest and a winding, glassy river. The foreground features a reflective stream that mirrors the vivid green arches, with smooth stones and a fallen log along the bank. Dense pine trees line the riverbanks, their silhouettes crisp against the luminescent sky. Snow dusts the ground and frost clings to branches, catching emerald highlights. The scene is bathed in a cinematic glow with a subtle long-exposure feel to emphasize the aurora's fluid motion. Composition uses the river as a leading line toward the glowing aurora, creating a tranquil, cold atmosphere with twinkling stars and distant mountains in the background. Ultra-detailed, hyper-realistic, vibrant greens, high contrast.
