Synthwave 80's style landscape

I've been already familiar with this style, but only not too long ago I stumbled on a wallpaper in this style which sparked my interest for it again. So I decided to make my own synthwave style lanscape. The result seems to be ok. Let me know I you want them with the CRT scan lines.
I also tried to add a sort of nebula effect with lights, but it didn't work. For some reason the lights did not show up in Blender and the nebula was killing my pc. So I went without them. The CRT scan lines were added in Post.
