This scene captures a moment of majestic motion. The figure in their leotard is skillfully riding the horse as it gracefully moves in an elegant pattern. The horse is sashaying its legs around in time to the movement of the rider while they are calmly holding onto the mane and saddle. With such a beautiful image, I would recommend coloring it with a soft yet radiant palette. Perhaps the leotard in a warm brown tone and horse in a mixture of brown and white. The mane and saddle can be an array of tan, light and dark brown, while the background could be a subtle shade of blue. With this idea of coloring, the final illustration will be one of a visually evoking portrait.
