It's totally red stock actually. However Train wanted it blue.
Firstly I gave C4D and copy it as Lighten/Overlay. Then Smudged C4D and some effects more which I don't remember right now.
Then I used a star stock. Blury dots at left side come from that stock. I used a rain texture. It really annoyed. Because I copied it like 5-6 times and everyone's blending mode is different as well as their fills and opacities. -_- Then focal point effects like depth and sharpen. I don't have my own tricks to do this. :/ Later Adjustment settings, text, at last lightning.
