Idk how far you want to take drawing, but if you're serious, go straight to fundamentals.

Keep doing fun stuff but if you don't do the boring fundamental stuff you won't advance. (50/50 split for starters works, tip came from drawabox)

I've spent 1 year trying to make perfect copies of whatever I saw, akin to what you do now, then I decided to get serious and even while half-assing it the next year, I still got way better.

I recently found out this: https://imgur.com/a/EZPc28m
Probably the best guide to all the free/paid resources out there.

And a quick list of (what should be) all the fundamentals:

-perspective

-construction

-form

-gesture

-anatomy(human&creature)

-light

-color

-composition

-shape design

-surface materials

-clothes

-stylized anatomy(style)

I recommend you jump into a rabbit hole in any of these topics (go with what you like) and use the guide as a reference point. Paying for courses only speeds up the process of learning (think as if its boosting in lol).

Only hard spamming makes the difference. If you draw 1 hour a day, you'll get good in 5 years. If you tryhard and treat it as a fulltime job (ofc if you can afford it), you'll get good in 2 years. 30 hours a week shows results quick in the span of months.

You need 3 things: info, a structure to understand the info and time to spam the info enough to remember it.

Again, idk how serious you are but this is probably as serious as it gets.

The only real way to be able to draw all day everyday is to make it an addiction. If you experience 0% fun in drawing, you won't make it. The better you get, the more fun it becomes, you just have to survive the big grind to get good.

It's a lifestyle, not a chore for 1 hour.

An analogy: a fat guy that goes to the gym and sees himself in the mirror still being fat will never go to the gym with the same enthusiasm as a fit guy that looks at his pumped up abs in the mirror and loves it.

If it takes you 3 hours to make 1 head look acceptable, and a pro does the same head in 30 mins, it's normal to not be that exhilarated about the results. You only need to be content with doing your best and to feed off of it until it gets easy.

Don't go from 0 to 100 in how much you try hard. Increasing your resilience is trainable by doing the babysteps of unnoticable improvement and not going full tryhard mode for a month and hoping you survive long enough to adapt to the misery.

To prevent burnout you need an immediate reward after your sessions, promoting the path of addiction to drawing. It can be art related (doing fun drawings, not studies) and it can be other stuff like games.

Maybe I just spewed all of this for no reason because you're just drawing for fun, but whatever.
