A rectangular die-cut sticker design in urban street art style, with a dark concrete wall texture background, intricate red and white spray paint splatter effects, and aggressive stencil typography that reads Severna Armija in bold, graffiti-inspired letters. In the corner, a sharp silhouette of a football ultra holding a glowing red flare, with intense, determined facial features and a skin tone with a warm, sun-kissed glow. A sharp white border surrounds the sticker, isolated on a solid black background, created in graphic vector art style with bold lines, geometric shapes, and vibrant colors, conveying a sense of energy, passion, and rebellion.
