I'm getting my braces taken off but I don't know if my orthodontist did a good job? (Photos)

Hello, I have had lingual braces for around 2 years and my orthodontist told me I'm getting them off next month. I've noticed some of my teeth look weird like a bit croocked but he told me that there's no a problem. Could it be that my teeth are suppossed to look like this?
