Sumi-e ink wash samurai fox and rat illustration

Masterpiece Japanese sumi-e ink wash illustration of two anthropomorphic samurai warriors standing back-to-back in a calm yet powerful pose, one an elegant white fox with sharp ears and multiple flowing tails, the other a noble rat with realistic facial features and rounded ears.
