Vertical illustration in classic Disney 2D animation style (Golden Age Disney), soft rounded shapes, gentle linework, vibrant watercolor-like coloring, whimsical and charming design. A closed wooden arched door painted in deep royal blue, decorated with a winter night sky scene — golden and silver stars, a crescent moon, delicate snowflakes falling, and swirling frosty vines along the edges. The door is framed by a thick white carved nalichnik (traditional Russian door trim) with soft rounded edges, snowflake patterns, and subtle geometric ornaments. The door has a rounded arch top, decorative wrought-iron hinges shaped like ice crystals, and a small round window with a white lattice covered in frost. A brass ring handle in the shape of a tiny horseshoe. The door is fully closed. Clean pure white background, isolated object, no scenery, no burrow interior, no background elements. Vertical portrait orientation, 2:3 aspect ratio.
