How to get a basic locomotion with idle, walk, jog, run?

So I am creating a basic locomotion for this Third Person character. I want to have the player go from idle ->walk->jog->run based on it's speed and to turn based on direction. This is my animator control below:

And this my code for the controller:

      Animator anima;
     // Use this for initialization
     void Start()
     {
         anima = GetComponent<Animator>();
     }
 
     // Update is called once per frame
     void Update()
     {
         hDirection = Input.GetAxis("Horizontal");
         vSpeed = Input.GetAxis("Vertical");
 
         //If the Key W is pressed, character will walk else stay at idle position
         if (Input.GetKey(KeyCode.W))
         {
             animSpeed = 0.5f;
             animSpeed += Time.deltaTime;
             vSpeed = animSpeed;
         }
         else
         {
             animSpeed = 0.0f;
         }
 
         //If the Left Control Key is pressed, character will jog else stay at idle position
         if (Input.GetKey(KeyCode.LeftControl))
         {
             animSpeed = 1.0f;
             animSpeed += Time.deltaTime;
             vSpeed = animSpeed;
         }
         else
         {
             animSpeed = 0.0f;
         }
 
         //If the Left Shift Key is pressed, character will run else stay at idle position
         if (Input.GetKey(KeyCode.LeftShift))
         {
             animSpeed = 1.5f;
             animSpeed += Time.deltaTime;
             vSpeed = animSpeed;
         }
         else
         {
             animSpeed = 0.0f;
         }
 
         //Pass the animator parameters to following variables
         anima.SetFloat("Speed", vSpeed);
         anima.SetFloat("Direction", hDirection);
     }

I attached the script to the Character object. The character is still in idle position, even though I pressed the W key to play the walk animation. Can anyone tell me what am I doing wrong? And put me on the right path. Thanks...
