An art director is irreplaceable in any creative project. He leads the team, is responsible for the concept and its visual implementation, and makes sure that the work is completed on time. To succeed, an art director must have taste and imaginative thinking, understand fashion trends, and be a good manager at the same time.The skill of an actor is based on three things: the ability to speak loudly, clearly and clearly, to move beautifully and “speak with the body”, to be alive on stage, and not to portray a role. Our classes are based on the same principle. Stage movement works with the physical body, stage speech - with voice and diction, acting - with the psyche and self-expression. Children learn to be themselves, this is the first thing on which further work is built. For someone, the teacher quickly “picks up the key” and the child immediately opens up, while someone needs to do more exercises and trainings in order to accept himself as he is.
