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
