This is some thing I developed inside Unity 2017. The models I used are free one on Unity Asset Store and some are from the TF3DM.
I used a great asset By Unity called Post Processing Stack to give my scene a really nice cinematic look and adjusted some color grading. I also used Linear color space to give my scene a really nice lightning merged look. Used Point lights and Reflection Probes to give my scene a more downtown and alley look
Second asset I used is Prism Post Processing Asset
This asset helps me to give my scene a Great Bloom, Chromatic Aberration and a good Exposure which is changing the full scene mood just by few clicks
