I went through the pictures, very interesting. Some of them still have asymmetry post op- it could be due to lip positioning, the negative or black spaces in the mouth are uneven, and other facial features that dont line up like eyes, chin, jaw angles, nose etc. Asymmetry is very hard to correct from what I understand, and I see it strongest in case #2 and 3.
The girl in case #7 ended up with a beautiful result, slightly gummy, even if the teeth are somewhat uneven size wise she still looks like herself!
