I have many hobbies as there are so many interesting things. But most of all I like to draw. Drawing - art display things in a different pattern in the plane and in space. Many people want a good draw, but not all at once obtained. It will not work well to draw in people without talent to this cause. Since childhood I liked to draw. I did it everywhere: on walls, in books ... After I grew up and painting became my passion. I love the view of the famous artists because it helps me grow. I also like the work of artists and animators. Drawing for me is a way of self-expression, relaxation. I would like to continue drawing was not only my hobby but also my future profession
