jumping and landing workflow

okey when i jump, the jump animation finishs before the character lands , what i want is , example : if i jumped from a hill i want my character to repeat a couple frames from my jump animation till he hit the ground , and he will play the land animation , btw here's the script that im using ( constructor third person player controller )

 // ANIMATION sector
     if(_animation) {
         if(_characterState == CharacterState.Jumping) 
         {
             if(!jumpingReachedApex) {
                 _animation[jumpPoseAnimation.name].speed = jumpAnimationSpeed;
                 _animation[jumpPoseAnimation.name].wrapMode = WrapMode.ClampForever;
                 _animation.CrossFade(jumpPoseAnimation.name);
             } else {
                 _animation[jumpPoseAnimation.name].speed = -landAnimationSpeed;
                 _animation[jumpPoseAnimation.name].wrapMode = WrapMode.ClampForever;
                 _animation.CrossFade(jumpPoseAnimation.name);                
             }
         } 
         else 
         {
             if(controller.velocity.sqrMagnitude < 0.1) {
                 _animation.CrossFade(idleAnimation.name);
             }
             else 
             {
                 
                  if(_characterState == CharacterState.Trotting) {
                     _animation[walkAnimation.name].speed = Mathf.Clamp(controller.velocity.magnitude, 0.0, trotMaxAnimationSpeed);
                     _animation.CrossFade(walkAnimation.name);    
                 }
                 else if(_characterState == CharacterState.Walking) {
                     _animation[walkAnimation.name].speed = Mathf.Clamp(controller.velocity.magnitude, 0.0, walkMaxAnimationSpeed);
                     _animation.CrossFade(walkAnimation.name);    
                 }
                 
             }
         }
     }
