Create an artwork depicting two children building a snow sculpture in a winter landscape. The scene is set in a snow-covered park, with details like snow-laden trees and a distant snow-covered bench. The children are focused and joyful, one wearing a bright red winter coat and the other in blue, both with hats and mittens, showing their expressions of laughter and concentration. The snow sculpture is in the process of taking shape, showing the creativity and playfulness of the moment. The light is soft and diffuse, suggesting a late winter afternoon, casting gentle shadows and highlighting the sparkling snow around them. The artwork should capture the warmth of friendship and the magic of a winter day, evoking a sense of nostalgia and the joy of being fully present in the moment.
