Very quickly I am blocking in the shape and all the large tonal areas . I am now ready to add some body to the paint. I will move to the sky next but keep going back into the boat defining the shape of the sailors and and putting in the darks and mid tones of the deck and boat body. I will leave the lights, or create them with a small cloth( rubbing out paint) This is typical of how I build up a painting. I will be able to cut in with thicker paint at a later stage to define the the edges of the boat and sailors.( That's the fun part)
