Rooble operates exclusively with spray paint and works freehand, a choice that sets him apart from many contemporary muralists who use stencils or projectors. This method transforms the act of painting into a virtuoso performance, connecting the monumental scale of his works to the intimate, deliberate movements of the human hand. His creations are based on his own photographs, which allows him to maintain full creative control and gives each piece a personal origin story.

Kitsune Jolene, a Belgian muralist, is a significant figure in contemporary street art, celebrated for her emotional, narrative-driven works. Her 2023 contribution to the Waterford Walls festival, "What Are You Waiting For?", stands as a powerful example of her focus on self-worth and emotional independence. The mural's message, conveyed through the artist's own public statements, delves into the process of internal growth and personal fulfilment. While this specific piece is her only known commission for the Waterford Walls festival to date, she has a sustained engagement with the wider Irish street art scene, with previous work in Cork.

The process of a mural's creation is a public one, and the period of observation—the daily transformation of a blank wall into a vibrant canvas is a key element of the festival's design. The festival is a social enterprise with the explicit mission to "transform and regenerate urban spaces" and "inspire and connect communities." By documenting the work's evolution, the photographer becomes an active, engaged participant in this process, fulfilling one of the festival’s core objectives. The fact that the photographs capture a unique, transitional phase of the art is a powerful demonstration of this principle; the value of the art lies not only in its finished form but also in the community engagement it fosters during its creation. This in-person, dynamic experience is often valued by the organisers over a static, finished photograph.
