I guess I could have expanded on my question. The core of it is 'how serious are you about this?' I'd like to get a handle on just what question it is that's looking for an answer.
Is it something you've always done, or something you tried to pick up in later life/after childhood? Do you just want to be able to express your thoughts to your own satisfaction, to impress or do things for others, or to turn it into a side gig or even a career? Have you ever tried looking for a teacher or learning resource?
I don't know how well I could answer anyway. I'm still wondering about some of those questions for myself. I think a lot of it comes down to this:
I've never considered quitting drawing because I think I would die if I stop.
I get this completely. I won't compare it to breathing or eating, but drawing is just part of me. I might have slowed down at times but I never considered
quitting since the first time I laid my chubby mitts on a crayola.
That doesn't mean I don't sympathise with those who struggle with it, who haven't drawn anything since they put down the crayolas and discovered outdoor games instead. It is a struggle. It will always be a struggle. There will always be someone better than you. There will always be
loads of people better than you. There's the common saying that an artist is never satisfied with their work - that a piece of art is never finished, only abandoned. You shouldn't let it hold you back. There's no shame in not being Kim Jung Gi right off the bat.
At the same time, I find it difficult to see the thinking behind 'I quit a while ago' or 'I'm quitting now'. If it's not in your blood, so to speak, if your hand doesn't grasp for a pencil when you're bored or stimulated, if you've no other outside motivation or compulsion pushing you forward - is it really going to leave a gaping hole in your life? I don't mean to say "go on and quit, you loser!" Just to seriously evaluate what you want to do. Is there any other, more enjoyable or fulfilling path you could direct that energy down? Would you be content with phone-pad doodles, or occasionally scribbling down a nice still life or your favorite character?
It's not an either/or question, of course. There's a sliding scale where you might be satisfied with your own skills, and there's nothing wrong with doodling what takes your fancy. I think there definitely needs to be at least a little direction, though.
Look at Stan Prokopenko's channel on youtube. He has a stupid amount of free instruction up there, beside his premium material. James Gurney has a blog heaving with art advice, information and examples, including drawing. Glenn Vilppu has a good online course too, from what I hear, but I've always been too cheap to check it out. Go look at Drawabox, like
@JuanButNotForgotten.
Try to find books by Andrew Loomis, George Bridgman, Marcos Mateu-Mestre, Gurney and Vilppu. Take Burne Hogarth with a pinch of salt. Avoid books by Christopher Hart or any no-name comic artist.
Keep an eye on contour, proportion, and three-dimensional mass. Study anatomy, perspective and composition. Use photographs for reference if you can't get out to look at a thing and its 3D form in person, especially in plague year. Video is a decent compromise between the two. Do you have favourite artists? Emphasis on the plural. Do they have art books out? Do some study copies of their work, but try to see just what they do and why, rather than mindless imitation.
Find some better instruction from someone other than some babbling rando on Kiwi Farms.
I have like procrastination/motivation/commitment issues
Unfortunately this is also just part of me.
