So, here is my Toy Truck submission link. Sadly, I lost my file with this materials setup, so I decided to make a new one for EEVEE lighting, so the colors a different. First thing I noticed – the world light was too bright so I reduced 5 times. Then I reduced F-Stops on camera to 3 and enabled DoF. All “suns” also have “Contact Shadows” checked and color and energy params transferred from the material. And SSR, AO, DoF and Bloom settings of EEVEE are enabled. Also, I put irradiance volume on the scene and baked indirect lighting, not sure, if it helps a lot.
Here are both renders.
