Do you just want to improve the frontal view of your nose?
Seems like you are happy with your profile and don't want to change that?! Which is good.
I had a similar looking tip of the nose, but I also had a bump in profile.
I had a nose job 11 months ago. I didn't get quite what I wanted.
I think what you are thinking of getting - thinning and slight elevation of tip is not that difficult to do.
It would make you look even better looking.
I don't really notice your face assymetry - we all have it, so don't obsess over it.
If you do get the rhinoplasty, make sure you communicate to your surgeon what you want exactly.
P.S. I never knew Blake lively had a nose job?!
