Pastel is a painter and architect. His work is rooted in historic events and the physical places where they unfolded, developing these as themes through the lens of personal experience and interpretation.

In his compositions flora, fauna and natural landscapes are both descriptive and conceptual tools that represent a place and symbolize the events that marked it, resulting in artworks that stand as contemplations of the dialogue between mankind and space, and the confrontation between industry and the natural world.

Pastel incorporates a range of different methods and mediums in his art, including technical drawing techniques, watercolor and gouache. A harmonious balance between different styles and techniques characterizes his organic, figurative pieces.
