Painting at Potholes Coulee

Last night I stayed at Red Lion in Wenatchee and rode down to Pothoses Coulee area and painted Dusty Lake from above. Shapes are probably ok but colors are not what I intended. Left side bluff is too purplish and the right side is too burnt sienna like. I might try putting burnt umber to the pallet again next time. Darkest dark is always purplish.
