Should I get a second opinion on my veneers or keep having my current Dentist try to fix them? (Photos)

I had gotten porcelain veneers placed on my 4 front teeth 5 years ago and loved them! Fastforward 4 years later and one of my front veneers chipped. My dentist decided to replace just 2 of the veneers and then it started my train wreck I'm currently in. My smile looked very unproportional to me, so he agreed to redo all 4 front veneers again.He finally redid all 4 and I'm still unhappy with them. Should I go in somewhere else to get another opinion, or try to get him to fix them yet again?!
