Small bonus: here's a timelapse of working on the lines and colors of the Eggren drawing! Very short since it's unedited and exported straight from Clip Studio Paint.
I am sorry to now show the sketch stage, I often draw sketches into one big document and then copy+paste the sketches I want to use to new canvases to start working on them from there. And I namely do that because it's less intimidating than starting a new canvas and drawing straight on there. I usually like to adjust the cropping/canvas size which seems to do funky things to the recordings after the fact.
This is why I like livestreaming when I doodle, cause that'll usually show my process of doodling and then finetuning to get a pose and composition how I want.
