How do you actually get better at making music...

you don't get 'better' you just do it and see where it leads

find a discord server or a website on the internet that has an audio section and publish your stuff on there, check out other outsider artists, give feedback on their stuff, that will also motivate them to check you out and give you feedback as well.

imitating is really gay lol making art to be like someone else is like trying to live someone else's life i.e. for retards and faggots

idk finding a good place isn't that hard. you could go to newgrounds or something, that's what I've used. it's mostly shit music made by kids but you will find some okay people after some time

Does anyone upload classical type stuff to newgrounds?

I've heard some.

Stay outside in the woods for 24 hours. Enjoy nature sounds. Stay silent. Probably stay awake during the night and sleep in a dry, warm spot in the pre-afternoon when some sunlight is available. Maybe see if you can manage 3 hours of rest. Then go back and listen to your tracks and decide which ones are more grating than others.

I love nature. So did Mahler and that didn't do anything to help make his music more enjoyable. Maybe half the problem is how much I love Mahler lol.

people love Mahler. Its just this garbage antisemitic cesspit that hates him. Mahler packs concert halls.

The key is figuring out which one of those off kilter dissonant ideas is the one that would make you experimental in a good way
