A number of people understand the traditional masks of various tribes with their tongues sticking out as a fear and respect-inducing way of intimidating the enemy.
In my childhood, I met such a beautiful colorful dragon. He was showing his teeth and stuck out his tongue, I fell in love with him. It wasn’t until much later that I found out that it was one of the “demons” from Sri Lanka, who primarily have a healing role, not a combative and destructive one. I tried to paint my “demon” with similar elements and immediately felt that I was looking into the kind face of someone I really like. It might scare someone and it is ok, some people find all my artworks scenes creepy, disturbing, or even repulsive. But I paint primatily for myself and for those who feel the same joy and peace in my paintings.
