Nathan Downie, known professionally as Nashīnasu ナシーナス, is a British artist working in anime-inspired surrealism. His practice explores emotion, perception, and inner worlds through painting and drawing, shaped by an autism-informed sensitivity to pattern, atmosphere, and light.

Working primarily in acrylic, oil, and graphite, Downie constructs cinematic compositions that sit between stillness and motion, each work conceived as a single frame from an imagined film. Light particles recur throughout the practice, functioning not as decoration but as perceptual markers: moments of focus, resonance, and emotional density.

Autism operates within the work as a perceptual lens rather than a narrative subject. It informs how space is organised, how light is experienced, and how meaning accumulates quietly rather than explicitly. The resulting works favour contemplation over explanation, inviting viewers to slow down and encounter familiar worlds through altered perspective.

Nashīnasu is positioned as a long-term artistic practice, producing singular works and limited editions held in private collections internationally.
