Share a little about the materials, processes and techniques used to create this piece. I have been watching Kathleen Moore's lessons. I graded the sky with white, yellow ochre, manganese, switching to pthalo and then ultramarine at the top as Kathleen suggested and it really helped make it more realistic. I'm using acrylic paint on board but will next switch to canvas. The clouds are a challenge but I think Kathleen's methods are really helping. I've wanted to do realistic clouds for awhile so I'm happy to watch a master.
