large-scale graffiti art on a sprawling urban wall. The graffiti is done in a wild style, featuring intricate, overlapping letters and vibrant, clashing colors that create a sense of movement and depth. The first line of text, 'WINNING MIND', is painted in bold, exaggerated fonts with sharp angles and curves, using a palette of electric blues and vivid greens to symbolize energy and health. The second line, 'Mafia Time', follows beneath in a daring, aggressive font, crafted in striking reds and oranges to stand out and provoke action. This graffiti is set against a backdrop of a busy cityscape, with the wall taking center stage in an otherwise gritty urban setting, showing elements like distant buildings and faint city noise, adding to the street art's authentic feel
