Do these crowns look right for my face? (Photo)

In the pic I’m wearing a composite of my crowns. I’ve gone back and forth with the dentist several times and this is what we came up with. I still think they could be a bit bigger, or perhaps just longer. I don’t want them to look fake either, want the teeth to have ‘character’. Honestly, I’m not even sure at the moment. I’ve been looking at this for too long. What do you think?
