An arm submerged in bathwater wears a black sheet mask with cutouts for eyes and a nose. The mask conforms to the arm's curvature and has a textured surface. The skin is visible through the cutouts. The arm rests against the white tub's edge. The water appears clear and still, adding to the relaxed atmosphere.
