Answer 1

The illustrator draws in the program in which he is comfortable. Everyone decides for himself what is more convenient for him. He can draw at all on paper without a computer. But it is in fashion now to draw on a special drawing tablet .
The program or device used does not in any way increase the drawing skills that can be obtained, for example, in an art school. So if you don’t have a soul for drawing, then it’s easier to hire a specialist, rather than do everything yourself.

Answer 2

Answer about software: I saw that someone draws in Krita This software (like any other) will not make you a great artist, but it will make some things easier to do.

Answer 3
