I have a slightly deviated septum and my nose tip drops down to the left side. Is this correctable? (Photo)

All people have facial asymmetry. Looking at your pictures your face is not particularly a symmetrical. I don’t see the need for surgical intervention regarding facial asymmetry or crookedness of your nose. I think your degree of symmetry is very much within one standard deviation or very normal.
All people have facial symmetry. The entire human body is highly asymmetrical. During embryological development, the two sides of the face form independently from each other, and eventually fuse in the midline. Even great classical artists have throughout time incorporated, facial symmetry into world, renowned classical works of art throughout the ages. The human brain is accustomed to seeing faces as being a symmetrical, since no one has a symmetrical face. If you see computer generated symmetrical faces, they have an odd unfamiliar appearance that most people find less attractive than the normal, balanced asymmetrical face of average people.
Symmetry is not, and should not be an aesthetic goal because the human face is never symmetrical. Facial balance is the hallmark of facial aesthetics.
I personally don’t see any need for intervention, but you can always consult with plastic surgeons who can very easily come up with good reasons why you should have surgery.
