Find a photo you like to emulate - this will show you what to do. Don't ask me any more questions until you can put your experimental rendering up against a real photo as a guideline so we can refine the rendering with an objective in mind.
This is going to take ten or twenty renderings to refine. Are you ready for that? Then you'll know something worth sharing.
Golden - the color of gold, like warm light from an incandescent lamp, not intense and almost white like sunlite. Look at a 40 watt lamp bulb - the color it casts.
I don't make night renderings because I am afraid of the dark - see the ArchiCAD library or look at an architectural magazine. - the cerulean blue/black at the top fading to the just-after-sunset-skybluepink color. What you are using is garish.
Experiment - start all lamps at 10% and go up in 5% increments until you actually know something about how lamp intensity works.
Never use camera light. Never is the right time to use the camera light. NEVER!!!!!!!NEVER!!!!!!!NEVER!!!!!!!NEVER!!!!!!! I mean - what the hell light is the camera light??? - a big bulb on your head - I already teased you once in your interior rendering for using it and making that horrid glare spot on the inside glazing. Wake up and smell the burnt ends of the torn out lamp from your head.
Start with ambient at 10% and work upward at 10% increments. The objective is to eliminate black shadows - black anywhere. Usually for an interior I set ambient to 100% unless the walls are white which I'd never do.
You don't need windolites in an exterior night rendering. Use the Sky Light set to dark blue. Experiment.

Then you'll know.
