Delay in 2D animation (Unity 5.0.2f1)

Hello guys! I'm trying to animate my 2D character in unity and everything is going fine, but I'm having a little delay when I stop pressing the buttom to walk (the animation still a bit more after I stop pressing the buttom).

Here my animation script:

using UnityEngine;
using System.Collections;

public class PlayerAnimation : MonoBehaviour {

public Animator anim;


void Start () {

anim = GetComponent<Animator> ();

}


void Update () {

if (Input.GetKey (KeyCode.A)) {
anim.SetBool ("Left", true);
anim.SetBool ("Right", false);
anim.SetBool ("Down", false);
anim.SetBool ("Up", false);
}
if (Input.GetKey (KeyCode.D)) {
anim.SetBool ("Right", true);
anim.SetBool ("Down", false);
anim.SetBool ("Left", false);
anim.SetBool ("Up", false);
}
if (Input.GetKey (KeyCode.S)) {
anim.SetBool ("Down", true);
anim.SetBool ("Right", false);
anim.SetBool ("Left", false);
anim.SetBool ("Up", false);
}
if (Input.GetKey (KeyCode.W)) {
anim.SetBool ("Up", true);
anim.SetBool ("Right", false);
anim.SetBool ("Left", false);
anim.SetBool ("Down", false);
}
if (Input.GetKey (KeyCode.A)) {
anim.SetBool ("WalkLeft", true);
} else {
anim.SetBool ("WalkLeft", false);
}
if (Input.GetKey (KeyCode.D)) {
anim.SetBool ("WalkRight", true);
} else {
anim.SetBool ("WalkRight", false);
}
if (Input.GetKey (KeyCode.S)) {
anim.SetBool ("WalkDown", true);
} else {
anim.SetBool ("WalkDown", false);
}
if (Input.GetKey (KeyCode.W)) {
anim.SetBool ("WalkUp", true);
} else {
anim.SetBool ("WalkUp", false);
}


}
}

Here a screenshot of my Animator tool:

My animation have one Idle sprite, a "start walk" sprite, and the animation that have 4 sprites, with 0,06 seconds between the sprites. Maybe someone here know what is happening?

 

Well, I think I fixed the problem xD haha. I will put here if someone have the same problem:

I realized that my "Walk" parameters on Animator was with a low value on speed. I increase the speed of the Walk parameters to 1.8 and now is working fine. By the way, thanks everyone!
