>>3814058What he is trying to say is which specific books/sources do you use to learn (obviously on internet).
Personally, I just go to any tutorial on youtube or Pinterest; and maybe twitter, which is a good place if you follow the right people. I don't remember their names rn but try to look for them. In my opinion, speedpaints are also a good way to teach more about painting, since you can obtain more ways or techniques to paint digitally. Just type "____" eedpaint and choose the style you like the most.
