I'm glad I helped. Draw a Box is unique in many ways, as you have said. And if I had to choose only one paid resource, I'd invest my money here.
That said, and assuming you are in the broad spectrum of the beginning stage, here are some free resources I would definitely check out:
You can take the 14 days free trial on Skill Share and study Marco Bucci "Understanding and Painting the Head", which costs 30 dollars on his site (and maybe come back in the future and buy the course to support his amazing work).
Proko, as you probably know, shares free versions of his premium videos on Figure Drawing and Anatomy.
The New Masters Academy has grown a lot in the last years and now it's offering is incredibly vast and better structured. With the 7 days free trial, you can follow Steve Huston Beginner or Advanced Head Construction, or his beginner course on Figure Drawing. Or choose a course from some other master. I would avoid painting because painting courses easily reach 40 hours of content.
Dorian Iten offers one of the best paid course on Light and Shading, but you can find a mini version of the course on his site with the formula “pay what you want”.
Ctrl+Paint offers a huge amount of free content on digital painting.
I don't know if you noticed, but in his last tweet Uncomfortable shared the old Draw a Box lesson on Composition. Good stuff for free!
