I am sorry to hear that you are unhappy after your Rhinoplasty. I have not examined your nose, so I must add that disclaimer but from the photos that you provided it does appear that your nose has at this time:
an open roof deformity from over-resection of the nasal bones
an over-resection of the nasal tip cartilages
You are about 3 months post op from your original Rhinoplasty and in another 3 months would need a revision Rhinoplasty to re-break and close the nasal roof and/or add a dorsal graft if the nasasl bones are of insufficient height to meet in the midline. The nasal tip could be softened and make more symmetric with a conchal cartilage ear graft placed in the nasal tip.
It's always best to try and have the original surgeon do the Revision Rhinoplasty unless you do not feel that you want to continue with him/her, in which case you would need to have consultations with plastic and cosmetic surgeons with good reputations performing Revision Rhinoplasty.
