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 midnight blue, decorated with a festive winter night scene — golden stars, a crescent moon, falling snowflakes, small glowing lanterns, and swirling frosty floral patterns. The door is framed by a thick white carved nalichnik (traditional Russian door trim) with soft rounded edges, star patterns, and geometric ornaments. The door has a rounded arch top, decorative wrought-iron hinges shaped like snowflakes, 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.
