The layer of the sun must be in the same tone of atmosphere.It was therefore necessary to rework on the lighting. For this I used the tool density plus / minus of flattened DARK mode of fusion. The sky is more cloudy and a gradient yellow to accentuate the brightness. For me, regardless of losing the details on the 3D object, the essential is the ambience!
Shadows and Light follows Continues to contrast the image and I added bright spots on the car and the lighter areas on the building.The headlights are just the points with a diffuse outer glow. They let off a little foreground and appear to be soil texture.
Asphalt The addition of the road was done using multiple images and mixing all the texture of asphalt. I also added a few more posts and a small fence to help the prospect. There's also a little more work on the soil texture to the station and under headlights.
Creatures and construction
Finally for mechanical spider I simply used construction equipment. I added a few elements in a body painting and a few lights. The technique for setting the background is the same as that of the car.
Hope that this small making of could be useful for you.
