Certainly improvements can be made but with any surgery one must gave realistic expectations. I think it would be difficult to achieve the appearance of the nose on the right.
That said, cartilage grafts could be used to smooth the indent you referred to . Combined with tip revision, I think you would be quite pleased with the appearance.
I would recommend tip revision either with further sculpting of cartilage and/or suture modification of tip cartilages.
Revision rhinoplasty candidate
Revision rhinoplasty Is always more difficult than a primary rhinoplasty due to the previous alterations in the anatomy, scar tissue formation and the overall healing process. The bulbous tip can be narrowed with suture techniques to the lower lateral cartilages and osteotomies of the nasal bones can create more definition in the sidewalls of your nose. It's a good idea to visit at least 3 busy revision rhinoplasty surgeons to get a feel for what can be accomplished so that you can have realistic expectations.

Yes your nose can be improved with a second rhinoplasty. No one will promise you the model's nose
