A realistic gray rat with fine details, depicted in high resolution. The rat has long, flowing fur that shimmers in vibrant rainbow colors, with smooth transitions between the hues. The fur is glossy and slightly strand-like, with a subtle textured surface and holographic glitter that sparkles softly in the light. The background is simple and dark, with gentle holographic glitter effects to enhance the vibrant colors of the fur. The lighting is soft and creates subtle highlights on the fur, making it appear dimensional and vivid. The focus is on the rat's head, especially the shiny eyes, pink nose, and fine whiskers, which are realistically and delicately drawn. ~16:9
