Unhappy with upper teeth after Invisalign refinements, bonding? (Photo)

My orthodontist told me this is the final result and we won't achieve anything else with Invisalign. I'm not happy that the gap between my central and lateral incisors on the left is not symmetrical to the right, and one of my front teeth is still positioned sideways. My ortho says it's the shape of my teeth, and I should try bonding, but I really don't want to do it unless nothing else can be done. Can traditional braces potentially shift my teeth further? Should I get a second opinion?
