Tired, so might not be expressing this well, but: I also think all artists gain something by trying to value and see beauty in all art, even the “bad” sort, by themselves and others.
Art with wonky anatomy or shaky lines etc is not just a necessary step on the road towards Actually Good Art, it has value for what it is right now, as an earnest attempt to capture Something with it’s own rough but unique charm. Every artist has a unique vision and something worthwhile to say, no matter how long they’ve been creating or how polished that art is. If you look, you can usually find real beauty in it, even something to learn from.
It’s ok to prefer more clear and polished art, and try to work towards being able to create that yourself, and to encourage other artists to work towards this as well as they can with advice etc. But that journey is long and difficult, and I think much more enjoyable and attainable if you can always appreciate where you or someone else is right now as having value in and of itself, not just as a stepping stone.
So yeah, support new artists. But not just to help them become better. Also because they are making art right now and THAT art has value as art, regardless of what they do or don’t end up creating later. And not just because this helps them, but because it helps you.
Specific personal context: spending time in Stardew Valley mod creation circles, which is full of art by programmers and teenagers. My regular art is usually “better” by most conventional metrics, but my pixel art is often “worse”, because I’m less practiced at that. But we can all learn from each other and appreciate the beauty in each other’s work. And Stardew Valley’s canon art is not “good” by many standards despite the creator spending years working to improve, and the original game art was even “worse”. But even if he never gets “good”, even if it had stayed like it was at the start, his art has still got a unique charm and it’s better than not having the game at all.
