Just realized something a bit more constructive... Since you have that warm yellowish backlight already, maybe the vehicle lights/glowing bits should be a different color, like red, or blue, for contrast. Feel free to ignore. Just popped in my head.
I would like to say that I have a plan but I don't. I make it up Which is why I have so much trouble duplicating these designs if I'm asked to do so because there's just too much shit to remember. Usually what I'd do is just draw blocks of colours as a silhouette, then I add the details in.
