One fun (free!) resource is DrawABox. Despite the humble name, you'll learn a lot more :)

Well structured, exercise-based, it takes you all the way from the absolute fundamentals.

I've heard great things about DrawABox and the works of Andrew Loomis: https://www.amazon.com/Fun-Pencil-Everybody-Easily-Learn/dp/...

Drawabox is excellent. What a delightful approach from first principles. I logged in to write it but I'm 2 hours late. It comes with a subreddit too learntodraw.reddit.com

I think the official "drawabox" subreddit is actually https://www.reddit.com/r/ArtFundamentals/

Both are great!
