Why shouldn't you do it again? Were you immediately good with a pencil when you decided to pick that up? :D

_{and don't try to give me any lip child I've seen your pencil drawings}

If it's any consolation I started off with two layers, one for lineart and one for colour. Then it became three, lineart, flats and shading. Now that's true for my sketchies and the bigger works, think one of my last ones ended up around a hundred (but I'm not sure how accurate it is as Krita keeps incrementing layer numbers by 1 even if you delete one) and I'm not convinced I'm using them "correctly" either.

Otherwise this kind of reads a lot like ye olde "the computer is doing it all for you", are we STILL not past that it's been over a decade for me now XD

but where does the value come from then, where is the competitive advantage when everyone can do the same, what is the point of trying to learn anything when it isn't necessary?

Because it's fun! :D
