I'd like a second opinion on my Invisalign treatment please. Unhappy with progress. (Photo)

I'm on my second refinement (3 more aligners to go). The canines still stick out too much but my dentist says my teeth are aligned if you look at them from underneath and it's because they're so big and fat that they stick out and there's nothing anyone can do. My laterals don't seem to be flash with my two front teeth either. Any advice would be appreciated because I just don't believe that I paid thousands to end up with a mediocre result like this or is my dentist right?
