Epic Game of Thrones-inspired Character Poster featuring a Northern Warrior

Create a dramatic Game of Thrones-style character poster. The image should feature a close-up of a young Northern warrior's face, inspired by Cregan Stark. He has long wet brown hair, pale skin, and piercing blue eyes. His expression is intense and solemn. The lighting is icy and blue-toned, evoking a deep winter atmosphere. Half of his face is in shadow to give it a moody, cinematic effect. Snowflakes are gently falling in the foreground and background. He's wearing dark Northern armor with fur, inspired by medieval fantasy. Use the color palette from the second reference image (dark greys, browns, and icy blues). In the center or lower part of the image, in elegant serif font, place the words: 'WINTER IS COMING'. The background should be subtle and snowy, giving a chilling and epic vibe, similar to official HBO promotional posters.
