Create a highly realistic Christmas-themed magazine cover featuring a blonde model facing forward with her eyes open and a regal posture, showcasing a long neck to highlight her festive attire visible up to her buste. The model should have long, thick silver eyelashes with blue highlights, and her eye makeup should be expertly applied in deep blue and silver tones, giving her a glamorous look. Her lips should be a bright, shimmering silver lipstick. Style her hair in a chic updo adorned with white snowflakes, silver decorations, and blue accents. The background should feature a gradient from deep blue to icy blue, with softly falling white snowflakes. Include a touch of sparkle to enhance the festive atmosphere, reflecting the luxury and spirit of Christmas.
