I did some photo documentation of the process.
My guide lines to simplify the scene:
1. More negative space. (lower horizon, expand space between cars)
2. Move the eye through the painting quickly. (clear path for the eye to follow the path of the road, narrow cropping)
3. Emphasis on on subject. (subject=where road leads, so up the contrast between the road/rest of the painting)
4. Keep one dominant color (easy, just like the photo)
thought i was done.
then decided to tone that car down.
