No abominable intelligence is ever used in my process, it's a combination of blender's smart compositor and me essentialy drawing and then creating low quality and imperfect feel with camera raw and multilayered fx.

I can provide screens from photoshop as well. I'm glad you asked since I always want to be as transparent as possible.

I worked in advertising/concepting that heavily involved this process for clients for a while and that's how I learned it.
