"Llumeru" is a travel under the sea, inspired by Verne and the Lovecraft's nightmares. "Llumeru", the new street theater show created for Factoría Norte theater company. A complex process of work in which I participated as art director, creating the image for the poster and merchandising, as well as the creation of each character. The first of the images corresponds to the prior advertising campaign expectation. The second, and subsequent, corresponding to the final poster of the show. My work finished with creation of the theatrical characters that build the show: Algamusa, Algamusina, Llumeru, Musitaño and Octocorde. The next images show the comparative between the initial sketches and the final and physical development.
