10 months after rhinoplasty - would I benefit from a revision? Concerned about bridge, nose hump, and dent.

It's been 10 months since my operation. I don't like the look of my nose. The bridge is wider in the middle and it still looks like I have a hump. Also, there's a dent on the tip. This nostril looks bigger than the other as well. However, there's scar tissue behind the dent which my doctor will remove. Would it improve its look? I also don't like how my columella looks, especially from the front. Above the incision is still swollen. Can my nose improve?
