You have to critically question the way you are thinking and talking about drawing. Often someone will tell me they feel their Ďproportionsí or 'anatomy' are wrong in comparison to mine. Instead a bunch of other ways you could talk/think about drawing is; 'do I really understand the form of this exact part before I put down a line? How does this mass relate to the torso/head/rest of the body as it balances, what sort of balance is going on? Is the silhouette clear? What is the best way to caricature this persons nose? Is that a thumb or a forefinger because I'm having to squint at the model to see it properly? Ah just make it up" My point is...good drawing is never just one element. Having an open, honest critical eye is the only way I've been able to grow. Perspective, anatomy, balance, solid form, are all elements of draftsmanship that need to be faced head-first.
I want people to know that many storyboarding jobs have become like 2D animation. I just speak on behalf of my experience making episodic animatics. It involves many drawings yes, but whatever amount you may be envisioning, imagine way more, and heaps of unseen drawings tossed out because they didn't serve the exact vision your directors had in mind. The concept of heaps of dispensable drawings is something that breaks a lot of artists. Mustering enthusiasm to embrace every new drawing is an attitude you either have or you don't.
In the end however, what matters more than drawing skill is always a love of art. Specifically, I don't think you can teach a love of characters and their stories. This is where my draftmanship argument falls apart, because I can't explain to people the wonder I felt discovering Inuyasha on early anime streaming sites. Alright I'm done for now. Thanks for sticking around.
