Pump - stage 1

Continuing with the theme of signs of human intervention in vast landscapes I decided to revisit a subject I painted earlier ("Rig") and have another oil pump in a vast flat Texan landscape. I didn't really feel that I had done the subject justice last time so this time it is the pump set against a flat horizon and a stormy threatening sky to try and get across the loneliness of the location. This is of course another painting in my The Big Sky  series.
This is the tonal underpainting stage which was "drawn" up with a small bristle brush using a mix of Burnt Sienna and Winsor Violet thinned with Liquin and then the tonal underpainting was dome with a rag using the same paint mix.
Oil on linen 30: x 20".
