SW06-2019 Seascape Plein air Painting 'Seascape Viewing from Dunes'
Here the beginning compo, ↪ big blocks of color.
And the end-result
Your Seascapes will get that spark of life in, when you can paint them there: standing on the beach.
Even if you don't live near a beach, you can book a holiday to a place near the ocean and start painting there.
