Chris brejon CG cinematography is amazing, not only there is a lot to learn from it, but its filled with link to other amazing resources, you can spend mounts exploring and learning.
Plus the way he share his experience is awesome and he talks with passion about how he experienced each movie he worked on.
To add up a bit to the conversation, the question is a bit tricky. Of course you can learn a few techniques that will help already. Is it really about making good lighting or good imagery in general ?
When you look at a shot from a pixar movie it’s a whole team at work. And a lot of planning is done by various department. It’s the same with live action :
These images got a very well crafted color scheme/palette. A lot of planning is needed to make sure the color of the character’s clothing is matching the set, the set match the sequence, that match the story… So everything is planned a lot before the actual lighting takes place, at which point these decision needs to be taken so when you are ready to film and light everything you need is there ?
With a good color palette and image composition it’s much easier to get a good image, you don’t even need to be super fancy with the lighting. A lot is about readability , which asks for simplification. Once things are simple it’s easier to make them go in one direction (the story).
But it’s also possible to do the same simplification by playing more with the lights, and less with the colors of the set :

The limited palette helps a lot to make the image simpler and easier to enjoy, but most importantly to support the story.
So yeah, I just wanted to mention that a lot is done to make everything support the story.
There is an idea, that is elaborated with characters, designs, sets, and lighting is just a new take on how to push these ideas further.
I don’t mean it’s always like that, a good colorist can probably save a poor image.
Same with a talented lighter like if they get on the set and nothing was planned they’ll manage to make the most of his light rig to support the story.
But with talented filmmakers everything is crafted from the beginning therefore there is nothing to save.
Hopes that helps a bit ! Have fun !
