Horse-Rider Pose Correction

I have a completed 3D scene of a horse and rider, but the rider’s body looks stiff and slightly off balance when the animation plays. I need a skilled 3D artist or animator to adjust the rider so the pose, weight-shift, and overall movement feel natural and in harmony with the horse’s gait...
