Is there some secret ingredient I've left out of my chicken soup that adds flavor?

I followed a copycat recipe of my favorite chicken soup from the restaurant Carrabba’s. I realized that the recipe probably wouldn’t turn out soup that tasted exactly like my favorite, but I expected closer than I’ve managed. The soup tastes good, but I’m missing something. I have noticed that 1) my soup is a lighter orange than the restaurant’s and 2) the restaurant’s soup has a nice spicy hint with every bite. Any idea what I might be missing? I’ve already included: carrots, celery, onion, garlic, plum tomatoes, potatoes, parsley, bell pepper, the hen, and all kinds of wonderful spices. What am I missing, what would add more flavor?
