If you want the secret to getting good at art it's legit just this btw
Fundamentals are a pain/sometimes boring to learn, but you'll be so much better once you have them solidified
If you don't care about improving then just draw whatever and have fun!
But if your goal is to REALLY ramp up your quality, you're gonna have to put in work to learn perspective/cubes/cylinders and do studies.
If another way existed I'd suggest it, but this is legit the only way sowwy :3c
