Is the cosmetic bonding too transparent? (photos)

Is the transparency of the cosmetic bondings on the two upper lateral incisors ok? Originally my upper lateral incisors were too small, so asked for a cosmetic bonding to make it look longer and thicker. Unfortunately, the result seemed thin and greyish (dead) to me. To improve it, dentist glued another thin layer on the front of my left teeth (right-hand side on the picture), which broke twice already and food gets stuck under it. I am not sure this should be acceptable. What can I do?
