Is it possible to become a good comic artist using only Krita?

I only use krita and I will always use that one, other software is too expensive and then they are different, it will take me a long time to adapt and I wouldn't have all my brushes, and since this is still a hobby for me, I would like to know if there are others like me and maybe they know a few more tricks to facilitate the process of creating comic/webtoon on krita.
