If you haven't heard of it, I really like the website ctrl+paint. There's a ton of free tutorials as well as extended lessons you can buy. https://www.ctrlpaint.com/

Hello JB2, learning art through digital painting or traditional is the same. The thing is to avoid getting too carried away with the medium/software and put it before the basics skills. It is tempting to use all these cool effects and brushes and often that is what gets in the way of progression as softwares are packed with it. Just know that it is probably going to happend to you. One of the best ways might be restrictions.Like use only round brush if you go with digital. Then Learn the basics : Perspective / Form / Light. Pick the ressource you like and study a little bit every day, read and re-read the same materials again and again until you undestand it. Then move on. It will take time but you’ll get there :) Hope this help !
