Regal frog king on a mossy throne in glowing swamp

A regal amphibian monarch, adorned with a tiny golden crown and velvet cloak, sits upon a moss-covered throne in a mystical, bioluminescent swamp. The surrounding flora glows with an ethereal light, casting dappled shadows on the water's surface. Giant lily pads serve as stepping stones, and fireflies dance in the humid air. The scene is rendered in a detailed fantasy concept art style, with rich, saturated colors and a painterly, atmospheric quality reminiscent of artists like Brom and Allen Williams.
