I've now added some depth to the sea, using the broad brush again to get the colours in. Using a selection of blue and green acrylics to get the light hitting the water. I've then used a dark shade of Ultramarine to pick out the drop in the waves, and to create a ripple effect. I used a very light blue shade to pull up the light on the top of the water and white for the crest of the waves. I've started to paint in a few boats drawing the simple shapes in white at first.
