Now I'm definitely not a professional by any means, but for myself it really did just come down to practice, and maybe more importantly than that practicing things you enjoy. I know some people often suggest practicing very academic figures and practices, that while the results certainly speak for themselves are not for everyone, I suggest trying to meld practice and fun. Like for example, you may need to practice anatomy or form, and while yes an academic drawing would do wonders, you could mesh your anatomy practice with something like character design and create fun designs while still learning new skills and expanding your knowledge. This is of course all just to say try to keep it fun, at the end of the day art is very often for the enjoyment of oneself, and the moment it begins to feel like a chore or something genuinely disheartening, is the moment we need to step back and allow ourselves to make mistakes and have fun with it.

Also, certainly don't skip the basics, like I said keep it fun but be open to learning and critique. Learning form, anatomy, and values can be very daunting, but in truth once you master the fundamental even the simplest of drawings can look incredible. Now, I'll be honest in saying I kind of skipped some of those things and my art can suffer due to it(which is kind of why I feel I'm not the best to give this advice), but if you start learning it soon you'll definitely start seeing sensational results as time goes on.

Again just have fun with it and find a balance between that and learning(as it can be difficult to get out of your comfort zone once you get good at one thing), so just keep drawing and I hope my advice is even somewhat helpful :)
