"A photorealistic skull with lifelike bone textures and sharp, angular features symbolizing the sigma identity. The eye sockets glow with an intense icy blue light, while subtle metallic engravings run across the surface, reflecting the name 'Skull Moments' in sleek, embossed lettering across the top of the skull. The background is a swirling void of dark smoke and faint neon highlights, creating an intense, larger-than-life impression."
