I think a good roadmap is to just really study some good drawing books from beginning to end.
Any Drawing book worth its paper is going to go over the most basic stuff, and what you feel you're missing out on can be addressed with another well regarded book.

It's likely why so many rave on about Loomis, because he's written several very good, well regarded books that essentially cover most aspects of drawing, so you could do far worse than just studying through all his guides as your 'roadmap' sorts - even the general order of his releases is a fairly decent way of going through them.

But really, any decent singular book will do wonders all the same. If you really need a starting point, and Loomis doesn't interest you because you're more into cartoons (and personally I think cartoons are the best starting point, as you're drawing simple shapes to construct characters - there's likely a reason Loomis starts with them too), I'd recommend Preston Blair's Cartoon Animation book.
