How do i create or start making art?
You can start reading the topics in this forum. See the art / illustrations, read the questions, the comments. You will find that there are many people who are starting out and others who have a little more experience. You can also start by looking at the basics/fundamentals of drawing and painting. On youtube you will find many teachings, exercises etc.
Krita will always be at your side for you to study drawing and painting.
