This is an amazing abstract scene which is made using triangles. The Key elements that helped in making this scene were:

* Creating Interlocking Pattern of Particles

* Color Management and Depth of Field

* Blue - Pink Gradient using Enrich add-on

NOTE: The Blue Evening Node group is not included in the .blend file. It is a part of Enrich add-on that can be downloaded from [blenderskool.cf/enrich](http://www.blenderskool.cf/enrich)

I have also created a tutorial so that you can create your own abstract scene: [https://www.youtube.com/watch?v=j5tZy9EJ1Uo](https://www.youtube.com/watch?v=j5tZy9EJ1Uo)
