Pascal Leyder lives near Vielsalm. In 2008, he discovered La « S » Grand Atelier and, after a successful trial period, began attending it regularly. Passionate about illustration, he produces numerous drawings very quickly, never correcting his lines. During the Ave Luïa project, Pascal Leyder readily put his graphic talents at the service of a collective project. He also took on numerous cathedral plans which, through their complexity, fueled his passion for drawing. His works often fill the entire sheet, combining labeled diagrams, writings, and identifiable signatures. His “punk” graphic style is frequently compared to that of the Pakito Bolino, with whom he collaborates on various collective projects.
