Using a dark mix of French ultramarine blue and burnt sienna I painted in the pupils of the eyes.

Using a wash of raw sienna I put down the under paint for the duck, leaving the whites of the eyes and painting around the bill.
With various mixtures of blue greys gradually the shading was put on the body of the ducky.
Finally the bill was painted using alizarin crimson, new gamboge, cadmium red and cadmium yellow.
