After septoplasty, my nose looks like its curving downward and nose tip is not sharp anymore. I wanted to know is this normal?

I just had my septoplasty 3 months back. Before surgery, my nose looked straight and both of my nostrils would appear even if I slightly tilt my head up but now they are not visible enough am I having retracted columella? when I smile my nose looks, even more, pointing downward also sometimes in the morning, my nose tip will become bigger and bulbous should I worry about this all Are there any exercise to straighten and sharp my nose I am hesitated to go for another surgery Thank you
