I am thinking about rhinoplasty. I want a Scarlett Johansson type of nose. Would that compliment my face structure? (Photo)

Rhinoplasty for reduction of the bulbous tip etc. Your tip is quite bulbous and can be reduced but not pinched if done by a very experienced rhinoplasty surgeon. See several whose noses you like and are natural nose results. 

Every nose is different and unique to that individual. If
the appearance of your nose concerns you enough to do something about it, it
can be improved with a natural artistically performed rhinoplasty. What would
be the best option and exact procedure would depend on an in
person examination (not just an online consultation) and discussion
about desired outcome. Excellent results can be achieved with either a closed
or open technique.
Keep in mind that following advice from a surgeon on this or any other website
who proposes to tell you exactly what to do and how technically to do
it based on two dimensional photos without examining you, physically
feeling your tissue, assessing your desired outcome, taking a full medical
history and discussing the pros and cons of the operative procedure would not
be in your best interest. Natural appearing results need to be individualized
and what is appropriate for one patient is not necessarily the best for someone
else. I would suggest that you find a surgeon with extensive rhinoplasty
experience certified by the American Board of Plastic Surgery and one who is
ideally a member of The American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable with. You
should discuss your concerns with that surgeon in person.
