abstract impressionism - working with design & color

This is on a large canvas - 2' x 3'. The underpainting is in acrylics, the final layer will be in oils. I'm enjoying working with the design and the colors. I seem to be leaning towards less and less detail as you can see by the photo of the last workup. I'm thinking of putting a semblance of a western rail fence on the horizon - not sure yet. Having a lot of fun experimenting - thank goodness for Photoshop! :-)
