Learn digital painting fast

Here is my setup and process

I want to learn digital painting. This may seem weird when Dalle2 is making awesome images just from text, but I want to extend and enhance images. I want to be able to create exactly what I have in mind, not play telephone with an AI trying to get close.

So I am going to learn digital painting. And I am going to do it fast.

Equipment and setup

Computer: Macbook Pro. Great computer and the one I use for everthing.
