I finished the illustration this early morning!
The watercolor brushes I was testing turned out to be very good! They allow you to smooth and blend colors without much effort and leaving good coverage without many layers. Clip Studio has many tools and resources available. I have downloaded several brushes, pens and pencils that I want to try.
By the way, I introduce you my two characters: Donoiel and Agramón. One is a fallen angel and the other a demon. Even though they are both on the side of the bad guys, they don't get along at all! So I wanted to draw them with a more human aspect and as friends enjoying an autumn afternoon.
