Revision nose and chin implant
If your nose still looks the same at the 6mo mark from your last revision, I would consider lowering the bridge and tip. The columella looks like there may be a graft there that is distorting it and may need to be adjusted. The chin implant can be switched to a larger implant - if you need a lot more augmentation, then the chin bone itself can be advanced.

Further improvements may be obtainable with a chin implant exchange and some additional tip work including alar rim grafts. You will likely come closer to 'perfection' in your chin than your nose as hard tissue augmentation is more predictable than soft tissue changes only.
Your nose looks fine --- maybe you would do better with a slightly larger chin implant. Remember - the enemy of good is perfection. The more surgery you have, often the more unhappy you get.
