Today's start....

Acrylic on canvas
30" x 30"

Palette:  Titanium white; Payne's grey, Windsor blue, Black, Raw umber applied with round and Filbert brushes and scratched here and there with a palette knife.

I think this is the structure and that when going back in I'll look for planes coming forward and receding clusters amplified with thicker coats and dabs of "dark" colors and shades.
