2.5 years after my primary DCF with rib graft Asian rhinoplasty and I'm not happy with the result. Options?

Notice the contour irregularities of my bridge. I believe that there is some built-up scar tissue or irregularities in the DCF that is making the left side of my nose look more full than the right. Will steroid injections be able to help with this asymmetry even though I'm 2.5 years post surgery? My tip is also very bulbous looking. I don't like how it droops, especially when I smile. I'm not sure if I have thick skin or not. Would I be able to reduce the tip without going though a revision?
