And there is also a very special series meant for Kids I haven’t mentioned so far even because it is for kids, but if you can ignore that these videos are addressed at kids, and maybe have a learning disability or ADHS/ADHD, then these can be great, because the vids are short and well explained, not too technical and good to grasp.
35-part Krita course for kids, but I think not only suitable for children:
