Got braces off after nearly 3 years and unhappy with results. What are my options? (Photos)

After getting my braces off I told my ortho at the follow up that I was unhappy and felt my midline was off. He dismissed my concerns. At the next appointment I want something done but am unsure how to go about this. I am really bummed as I paid over 6k, my teeth look terrible and I have no money to have further work done :(
