I used wacom intuos small and medibang paint pro.
-Wacom intuos small -
I bought wacom intuos small, an affordable tablet like a month ago because I don't know if I can be a real artist or not. I'm a beginner who just know what layer is, what's the differences between airbrush, g-pen and others . So if I don't have talent for this, I won't feel my money is being wasted too much on this.
-medibang paint pro-
To be honest, it is a bit hard to use medibang because it doesn't have slice tool and there aren't lots tutorial of medibang for making webtoon in YouTube but after a month of using it, I got used to it and it's not a big problem.
But still, it would be better to have Ps someday.
