I did 6 upper prepless veneers and I’m not happy with the results. Can I remove them without harming my original teeth? (photo)

My first two teeth have different shape and length. I don’t see much teeth when I smile ! Which was why I did veneers is mainly to show more teeth while smiling. I feel I didn’t achieve that. color wasn’t the same my dr and I agreed on. We did 5 mockups and I feel like my final veneers doesn’t match my final mockup ! I need your opinion? What should I do! I have health teeth correct bite
