>>6616543Sure thing man.
I usually start out with a good idea in my head.
I use Blender to create the majority of the image.
Render out a few different frames (there's usually noise, so you can average it out with multiple images).
Then I bring it into photoshop for post production. That's where a lot of the magic happens.
It's different for every wallpaper, but I do have a few steps that are the same throughout.
I start out with levels to bring everything together and get a good contrast.
Add some type of background. It depends on the wallpaper, but I use stars a lot.
Back in Blender, I usually render out an emission pass. This contains all the objects that emit light. Using that, I overlay that with some blur to add a tiny bit of bloom.
Vibrance and saturation to bring out colors after that.
The photo filter adjustment layer, usually set to cool.
Some added color correction with a color balance layer.
And whatever else adds to the image, whether that be a gradient overlay, random paint strokes for added effect.
Hopefully that helps out.
I know you said a light rundown, but this might help a bit better.
Pic related is OP's image before all the effects.
