What's my nose type and how can it be changed to resemble Angelina Jolie? (Photo)

Modifying the tip cartilages can make a big difference in the width of the tip of a nose. The woman in the short video that I posted with this answer had her wide tip address in her rhinoplasty.
Be sure to read the section in the "Learn more" link on how to stay out of trouble while searching for a rhinoplasty surgeon. Rhinoplasty is an exquisitely difficult operation to get right, and you should only have surgery if you are able to make yourself very confident in your surgeon's skills. 
Your nose with a wide tip is also a good example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. When you see his goals, you'll know whether he has an eye for an attractive nose, and whether he shares your opinion of what constitutes an attractive nose. You'll also know whether the changes he proposes are enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. How would you ever get that figured out without the morphs?! But remember, you're not hiring him for his skills with the computer. The doctor must then show you his before and after photos to prove that he can actually accomplish what he draws on the computer.
Finally, I usually make computer morphs when I'm answering a RealSelf question, to show the changes that are possible for your nose with a rhinoplasty. But unfortunately the photo you submitted isn't good enough for making morphs. At the *very* bottom of the "Learn more" page is a link to instructions on taking photos that are more comprehensive and useful for online consultations like this, in case you'd like a more complete evaluation.

Your nose could be improved with rhinoplasty, which would give permanent improvements in symmetry and shape. You can bring the photos of noses that you think would be flattering to your face and these can be discussed. When you meet with a facial plastic surgeon, he or she will consider your nose in balance with your other features and can over the cost of the procedure. I hope this helps.

I would recommend starting with a consultation with a board certified facial plastic surgeon that specializes in rhinoplasty surgery to discuss if rhinoplasty can address your concerns. 
I would recommend writing down the following questions before scheduling your consultation:
1. Are you unhappy with the tip of your nose? 
2. Do you feel that your nose is too wide? 
3. Do you want to make your nostrils smaller in appearance? 
4. Are you looking to decrease the general size of your nose?
I hope some of these questions will help you pinpoint what it is that you don't like about your nose.  Cost will vary due to various factors like anesthesia fees, facilities fees, etc. I wish you the best as you research your options when scheduling a rhinoplasty consultation.
Sincerely,
Philip J. Miller, MD, FACS Double Board Certified Facial Plastic Surgeon
