A Russian fairy-tale boy mouse wearing a blue kaftan with golden trim, a red sash (kushak) with tassels, a white kosovorotka shirt with embroidery, and boots. Vertical illustration, full-body shot of a Russian fairy-tale mouse in a cozy burrow, drawn in vibrant alcohol marker illustration style, reminiscent of children's storybook art. The mouse stands in the center and warmly extends one paw forward in a friendly welcoming gesture. In the other paw — a shiny gold coin. The burrow interior is identical in every image: a wooden table with a samovar and a burning candle in a holder, a small bed with a patchwork quilt and canopy, shelves with leather-bound books, a woven rug on the floor, clay pots, and an old pendulum clock on the wall. Art style: bold vibrant marker strokes, visible hatching and cross-hatching, kraft paper texture, sketchy whimsical linework, warm fairy-tale palette — deep browns, golden ochres, warm reds, rich blues. Background nearly black, rendered with soft marker strokes for velvety depth. Consistent character design, same lighting, same composition. Vertical portrait orientation, 2:3 aspect ratio.
