Welcome to the greater Hive art community. Some other places you could post to are #onchainart and #sketchbook.

I don't use Adobe. My program of choice is Clip Studio Paint. There's no yearly subscription, it's a 1x $50 price tag for the "lite" Pro version and even that has more tools and features than I know what to do with. They also have 50% off sales constantly. I think a lot of people use it primarily for comic or manga art, but I've used it to do oil paintings and charcoal drawings. Look into it.

Also, I've heard good things about a free program called Krita, but I've never used it.
