Santa street-art collage on concrete wall

Contemporary street-art collage of Santa built from layered torn posters on a rough concrete wall, fragments of red paper and white halftone dots forming his coat and beard, spray-painted snowflake shapes around him, stenciled reindeer silhouettes peeking from underneath, digital glitch effects running through the collage with RGB channel splits and horizontal distortion bands, bits of printed patterns offset like old flyers, gritty surface texture and electric urban energy
