Create a modern Christmas card with a high-quality, detailed digital illustration of Ded Moroz (Russian Santa Claus). Ded Moroz is depicted in his traditional long red and white robe with intricate embroidery, holding a staff topped with a snowflake. The scene is festive and elegant, with a modern touch—set against a winter backdrop featuring sparkling snow, pine trees, and glowing fairy lights. The composition includes thoughtful elements for teachers and educators: a beautifully decorated chalkboard with holiday greetings, books and scrolls tied with ribbons, and small symbolic gifts representing knowledge (like an open book or quill). The atmosphere is warm and inspiring, with soft glowing lights and subtle festive accents, while keeping the design sleek and contemporary. Text space is left for personalized messages
