The girl is looking resolutely to the right, at a specific, unknown point. The visible right corner of her mouth gives the impression of a slight smile. The model's shoulders are lowered. The left one, bent at the elbow, is placed horizontally along the waist. On it is stretched the body of a white ermine, whose neck and head are raised. The ermine is looking in the same direction as Cecilia. The girl's right-hand fingers touch the animal's fur at the neck, giving the impression of gentle stroking.
