Using a round 16 brush I used Cerulean, Cobalt, and Ultramarine Blue to rough brush an expressive and rhythmic sky and then repeated this feeling in the water. This sets the painting up for a bright summer painting. You will get a lot of mileage out of pure vibrant colors and a round brush, try to paint with all of you arm not just your wrist.
Use strong brush mark and the painting will be off to a good start.
Staying with the side of the round brush, add in some burnt sienna, new gamboge, olive green and thalo yellow green. Remember expressive brushwork and rich colors make a nice textural foreground.
Paint the land mass in the background starting at the top and work down to the water line, try to get a feeling of water splashing against the rocks. Scrape highlights of the rocks and down the face of the cliff. Put in some darker brush marks of ultramarine and olive green on top of the water to give it depth and movement.
