I chose this painting to practice sea washes... there is definitely room for improvement. It is again the Bay of Cadiz with Constitution bridge on the horizon.

The sky is cobalt blue, and for the sea I used a mix of French ultramarine with a small amount of permanent rose and raw sienna as well as Payne's grey with some cadmium yellow for a pale green. The paper is Arches 300 g/m2.

Comments welcome.
