Without all photographic views, including the base view (the one from below the nose looking up at the nostrils) I can not give you a specific plan to accomplish your goals. However, several options are present to derotate or drop your tip.
1) shaving the bottom of the septum can sometimes allow the tip to drop. Since it appears you do not need a lot in that regard, this might work well for you and would probably be my choice in your case.
2) trimming the tip cartilages right where they meet your upper lip can also produce derotation.
3) removal of bone near the base of your septum can add additional derotation if desired.
4) formal tip surgery involving sutures can be used to change the overall angulation to your tip. This can be tricky and I would not recommend this unless you need significant narrowing of the tip when viewed from the front.
May options exist and, if your surgeon is experienced in Rhinoplasty, whichever one he or she chooses will be based on their own past experience and success.
Good luck.
