What are some good free drawing/art softwares for PC?

So, I’ve been using paint.net for a while and it’s been getting quite old, I would like to know some free art/drawing software. Thanks in advanced!

Art related programs, I would personally go with Krita. Clip Studio Paint offers a 30-day free trial as well but I suggest looking into a program like Clip Studio Paint (Full Version) or Paint Tool Sai if you are more experienced and ready for a more professional program.

You can use Krita and FireAlpaca as free drawing alternatives.
