Brother Bear stands tall on a large, smooth rock in the middle of a fast-moving river. His mouth is full of a freshly caught fish, which he offers the bear cub swimming towards him in the water. The cub paddles forward, eager to reach the juicy morsel that it's older companion offers. To bring this picture to life, use a variety of blues and greys for the water and a brownish hue for the rock. As for the two bears, blend shades of brown for their fur and add some warmth by adding oranges and yellows too. Finally, to create a deeper sense of atmosphere, add some greens to the background to create an idyllic scene.
