This large, white rabbit looks curious and attentive, as though they are wondering what the viewer is thinking. The oversized key in their grasp gives the impression that they have something important to do. With a navy waistcoat, the rabbit looks sophisticated. The pocket watch dangling out of their pocket is slightly askew, suggesting a bit of mischievousness. To make this scene come to life, I would use bright and inviting colors for the rabbit's coat. The pocket watch should be a vibrant gold, and the key should be painted with a delectable shade of blue. Finally, by adding in a vibrant green background, the sense of adventure and mystery will be complete.
