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 whimsical mushroom-shaped door in Russian fairy-tale style, made from a giant mushroom cap. The door itself is the stem, carved with tiny windows, a rounded arch top, decorative wrought-iron hinges shaped like vines and leaves, and a carved wooden frame with geometric patterns. The mushroom cap forms a natural awning above the door, decorated with white spots and small glowing fireflies. 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.
