Cinematic Fantasy Portal Snowy Forest Portrait

Hyper-realistic IMAX-level Netflix-style cinematic fantasy portrait, 9:16 vertical. Use the uploaded image as the primary visual reference and preserve the overall composition and subject proportions. Create a handsome man wearing a dark gray hooded winter jacket, black pants, and dark shoes, walking away from the camera through a snowy forest. He is centered in the frame, seen completely from behind, with his hood covering his head and both hands tucked inside his jacket pockets. One leg is stepping forward while the other remains behind, creating a natural walking motion, with fresh footprints visible in the snow. A huge glowing circular portal surrounds him, forming a bright golden-orange ring of flying sparks. Inside the portal is a completely different lush green forest with a straight tree-lined path, creating a magical contrast between the frozen snowy world outside and the green world inside. Snow-covered leafless trees fill the outer background. Strong golden light radiates from the portal onto the surrounding snow, while the outer forest remains cold, dark, and blue-gray. Cool desaturated winter tones outside the portal contrast with rich natural green and warm golden tones inside it. Cinematic atmospheric lighting, realistic snow, glowing sparks, soft mist, dramatic depth of field, magical realism, high-detail cinematic photography.
