Your nose looks significantly better although I do see the deviation. THis can sometimes happen as a result of unroofing the curvature when the dorsum is taken down( rasped, etc.). At six months you still have swelling. You need to give it at least a year.
Your nose is still swollen and will settle for another six months and gradually go down. You need to wait for the swelling to go down naturally and if the nose is still deviated you need to see your surgeon.
The swelling will continue to go down over the next 6-12 months. You are still in the period where massaging the nose will be beneficial. Keep massaging and stay in contact with your surgeon. This may need to be revised at a later date if it heals in a crooked position.
Better series posted in this question. Appears you may need a revision surgery to improve the appearance..
