This scene features a robust saber-toothed tiger standing on a huge block of ice along with a mammoth and a sloth. The tiger's mouth is wide open, revealing its huge, intimidating, sharp teeth. The mammoth is large and has long tusks. The sloth is much smaller, with a little nose peeking out of its furry face. To bring this scene to life and make it look even more realistic, I would suggest coloring the animals in their natural colors. The tiger can be shades of yellow, brown, and white. The mammoth can be colored a light grey, with yellow and white tusks. The sloth should be a mix of light and dark brown. The icy block can be various shades of blue and white to give it the appearance of a snowy landscape. Finally, add some accents of black and white to bring the animal's features out.
