What happened? Is this worth revision?

One year post op and I am not happy with my result. I am breathing well, but I am not satisfied with the aesthetic result. Nostrils are retracted and columella is still hanging. . Surgeon said that the hanging columella is caused by the graft he put to support the nose from drooping. I am also afraid of messing my breathing since it was a revision for fonctionnal issues and aesthetic issues. What happenEd? Does it look like scar tissue?
