In this charming coloring page, three adorable little mice can be seen. The two standing mice are on their hind legs, while the other is seated. All three are the same shade of grey with white bellies, and all have their tails pointing up eagerly. They seem to be captivated by something off to the side, curious to explore what lies beyond their reach.
To emphasize the inquisitive nature of these three little critters, I would start by using brighter colors for their eyes. The two standing mice could receive some differentiating marks such as a bow-tie for the left one, and stripes on the face of the right one. All three could receive little mufflers or details on their cheeks and bellies, to make them seem even more gentle and playful. The delight of the scene could be brought out with light blues and pinks for the background, and details such as flowers and clouds. The little mice could all receive some different pastel colors, to give them an even softer touch.
