Berdalet's work is organized into different pictorial series. Constant study is an unbreakable premise. Listening and observation are characteristics of Marina, the painter and also the person. That is why each one of his pictorial series turns out to be variations on the same theme, which he gradually breaks down until the theme is exhausted.
