Create a hyper-realistic digital artwork featuring a large, impeccably clear ice cube resting in a serene, snowy environment. Encapsulated within the ice cube are vibrant pink roses in full bloom, exhibiting intricate details, from the delicate petals to the lush green leaves, providing a stark contrast to the frosty surroundings. The ice cube should display realistic textures, complete with elaborate frost patterns and air bubbles. The background is to be a subtle, soft-focus winter landscape with faint silhouettes of tree branches, all under a gentle and diffuse light that evokes the chill of a winter's day. The piece should embody the juxtaposition of nature's stillness and the enduring beauty of the roses, preserved in ice.
