Auto Trim - stages 1 and 2

The title refers to the sign although the main focus of the painting is the red building...which is not Lonnie's Auto Trim. Anyway I came across this in Knoxville Tennessee and thought it might be a nice subject for a painting. I'm trying to make a fairly ordinary urban scene much more interesting by painting it in a very moody and atmospheric way which also seems to bring out a somewhat surreal aspect to the scene as well. I first "drew" it up with a mix of Burnt Sienna and Dioxazine Purple and then washed in a tonal underpainting using the same colour mix thinned with Liquin and turpentine using a rag. The next day I put down a basic colour underpainting which begins to show the lighting and colours that I am intending to use.
