If there is one aspect that stands out in the work of Joan Castejón is his exceptional drawing skills, a palpable mastery also in his painting and leading to write to José Manuel Caballero Bonald "the artist draws a classic and meditate as a prophet". The author and official historian of Alicante Enrique Cerdan Tato wrote in El Pais on the work of Castejón: " ... he wanted to express the universe of man revealed by violence".
