As you point out in your post, the tip is still very projecting, and the nose is long, with the tip hanging down. Those are common results after rhinoplasty, because de-projecting the nose and elevating the tip require advanced work on the tip cartilages, places where many surgeons fall short.The good news is that 1) elevating and de-projecting the tip are two of the most predictable changes to make in a nose in expert hands, even in a revision, and 2) elevating the nose in particular helps expose the columella.See the "Web reference" link, just below my response: I made a computer morph, and an animation of the morph, to show what your nose might look like with the tip de-projected and elevated. If you watch the animation carefully, you'll also see that I reduced the strength of your nose up where it starts, just below your eyebrows. It's important to reduce that area if we want the nose to look less prominent.I don't see anything here that would require grafting.You should understand that the changes I demonstrated in the morph require advanced techniques, techniques that most plastic surgeons cannot handle. Be sure to read the section in the "Web reference" link on how to stay out of trouble while searching for a rhinoplasty surgeon.
