As for the photo:
Shoot during blue hour, focus on finding some good light source to illuminate your scene and compose so it's central point of interest in your shot. In postproduction raise blacks and whites on your tone curve for softer look (see picture for reference). Lower contrast and clarity can also help, just make sure you don't overdo it. Use split toning to get closer to overall orange-teal look. But it's kinda cliché these days.
