Three Labs Portrait, Background

Before starting the background, I painted over the labs with masking medium, to protect my original painting. I like to use masking medium so I can paint right up to the edges without too much fiddling.
I painted in the grassy area with a thin wash of Green Gold and Sap Green Hue. I deliberately left some texture so it wouldn't look too flat. I painted the mountains with a mix of Titanium White, Dioxazine Purple, Carbon Black and Burnt Umber, adding shading with Payne's Grey.
The next phase is the time-consuming task of adding the individual trees and grass texture. To do this efficiently, I used several different brushes, in different sizes, to make the individual marks. I mixed several different shades of green and alternated strokes in different areas to show depth. I put in the texture of the grass and flowers in the foreground using a fan brush. I painted grass over the dogs' feet, and put in some flower detail against their coats.
I painted in a thin glaze of Nickel Azo Yellow and over the grass to warm up the painting a bit.
