Why the new assets don't load from the resources folder?

Question

I have this script which is supposed to assemble a character on a prefab using sprite sheets, but nothing happens when I run the script. I think it might not be finding the files because Debug.Log does not give me any of the sprite's names. But the file path is definitely correct so perhaps its not finding the game objects on the the prefabs hierarchy.

public class Character : MonoBehaviour
{

IEnumerator Start()
{
    yield return PullAssets();
}

IEnumerator PullAssets()

This seemed to work

Sprite[] amazon_armor = Resources.LoadAll<Sprite>("New Art/amazon/revisions/armor") as Sprite[];
    Sprite amazon_armor1 = amazon_armor[0];
    GameObject ArmorBody = transform.Find("Root/Pos_Hip/Bone_Hip/Pos_Body/Bone_Body/Body/Armor Body").gameObject;
    ArmorBody.GetComponent<SpriteRenderer>().sprite = amazon_armor1;
