Paint in the light washes across the entire scene.

Then the shadows in the trees that wrap around the road sign and above the road, across the road, under the car then down into the massive foreground shadow - prepare enough paint, in varying shades and treat that as one shape. Basically everything you see when you squint at the photo.

Then add a few dark details here and there. I imagine the focal point is sort of in the middle distance looking down the road.

This visual cohesion will give you a greater of calm.
