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. 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 bright and shimmering silver. 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.
