A homeless man’s portrait on a subway station wall, with each tile making up his face revealing individual stories of struggle. street art portraiture with grid- based abstraction, bold stenciled figures with high- contrast realism, fragmented mosaic textures blending into urban graffiti, socially charged and thought- provoking themes, hyper- detailed faces dissolving into pixelated street patterns, black- and- white stencils combined with colorful abstract grids, pop- art meets political satire, layered and textured city walls with deconstructed portraits, raw urban energy meets meticulous realism
