Mariaceleste Arena uses pastels, acrylics, and digital techniques, enriching her creative journey with formal artistic training. She experiments with vibrant colors, glitches, and visionary elements that rework reality, drawing inspiration from outsider art and the nostalgia of the 1990s and 2000s. Her works express an emotional catharsis, intertwining irony, torment, social criticism, and a powerful energy that invites reflection on oneself and the world.
