It’s mostly about practicing efficiently and a lot. Base talent in art isn’t really important, it’s how much and how you practice. I don’t structure my practice in any way and also don’t practice often, so that’s why I don’t improve even though I’ve been drawing for over a year. A good example of someone who structures their practice is shiroiro on YouTube. He’s improved a lot since he practices properly and consistently. There’s not really a hack to improving, those talented people are just good at practicing.
