How risky is a revision rhinoplasty and can I recover characteristics of my pre-surgical nose?

Had a rhinoplasty done in May to get rid of a bump on the lateral side of my nose. The surgeon took too much cartilage from the right side and it is not symmetrical to the left. He also reduced my tip and made my bulblous nose pointy. I preferred my nose prior to the surgery. I had a bulbous but long nose and I would like to recover those aspects. I want to make the tip and middle section of the nose wider and longer like I had previously. I would also like to add cartilage to the right side. How difficult is it to revise my nose and go from my surgical nose to pre surgical nose?
