Create a stained glass collage artwork depicting a green frog resting under a green lilypad, surrounded by pink-white water lily flowers, an aqua blue pond from above, swirling orange and white koi fish, lily pads and lotus flowers, with rippling water patterns in turquoise and cobalt. Incorporate Japanese-inspired geometric borders, and use whimsical grey pencil, charcoal sketch, and charcoal greys to bring the handmade illustration to life. The overall aesthetic should evoke a sense of tranquility and wonder, capturing the serene beauty of nature in a whimsical and artistic manner.
