It's possible to become a better artist while going through a phase where your art looks worse. In fact, it's normal, and often being afraid of it holds back people's artistic development, because they're afraid to look like they've gone backwards, so they instead just keep drawing the same things using the same approach and they stagnate.
Example? Okay, I drew these when I was fourteen:
Holy crap fourteen-year-old me, those are some pretty good drawings for a fourteen year old, great job!
But then a couple of years later, I was drawing like this:
Urrgh sixteen year old me, this drawing sucks, why can't you seem to recapture those cool drawings you did back then?
It's because of the way child me approached drawing, and the way teenage me had to then break it in order to become a better artist. Child me was a perfectionist. She would work out how to draw one thing, and she'd break it down to a set of replicable instructions; line here, curve here, shadow always here. It's an approach that will allow you to consistently draw a good looking image of the things you have memorised how to draw.... but then whenever you need to draw something outside of that, like say, the character in a new pose or from a new angle, or two characters interacting, or heaven forbid, a new facial expression, it's going to look obviously worse than the established stuff you have. This also affects people who produce good art only when they're tracing or copying drawings from other artists; if they stop, their work looks worse, but they have to stop and go through that phase of kind of sucking or they'll only ever be able to make work by copying, and they won't develop.
So if you go forward another couple of years, you get work like this. Yes, this is a very unfunny joke. Yes, it's dog-face, yes there's comic sans.... but:
Okay, eighteen year old Kate, now you're getting somewhere. You've got the decent proportions of the stuff from when you were fourteen, but now you can consistently draw what looks like the same character, with the same proportions while deliberately depicting different poses, angles and facial expressions.
And then you get a stylistic evolution that looks like this, where that teenager keeps trying stuff out and eventually becomes a professional.
And you can see all the awkwardness around noses that happens during years of trying to work out what to do instead of dogface/triangle noses, and that some of it resulted in really weird, awkward, long faces and things. You can see how sometimes the pelvic region looks really awkward due to struggling with how the heck to draw it if I wasn't just hiding that area with character design or under-detailing to avoid even thinking about it. You can see how washed out the colour goes in the initial experiments with digital colouring. Periods of making work that looks weird or bad will happen. They're important.
Let yourself be bad for a bit and try things out. If nobody's paying you, there's no pressure for every piece of art you make to be production quality, or even "share online quality". Don't be afraid to make bad work sometimes.
