Crooked nose and bulbous tip? (Photo)

I agree that your nose is a little crooked but not bad.  Also your tip is bulbous and your nostrils flare.  These can all be addressed with standard rhinoplasty techniques.  It will however require breaking the bones and the nose may still be a little asymmetrical afterwards .

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

I made a computer morph of your nose, and an animation of the morph, to show the changes that are possible for your nose in truly expert hands.Mostly, I narrowed the two cartilages that form the tip of your nose. I also elevated the tip a bit, because when the tip cartilages are strong enough to make the tip wide, like yours, they are usually strong enough to hold the tip down, making the nose tip look a little droopy. Perhaps you can see those changes best in the animation. The woman in the short video above had all three of those features, too, although to a greater extent than on your nose.When the cartilages are that wide, it's almost impossible for them to be exactly the same in shape and size, and I'll bet that's what's causing the asymmetry that you see.
You should understand that the changes I demonstrated in the morph require advanced techniques, techniques that most plastic surgeons cannot handle.  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. Read that page very carefully. Most plastic surgeons are quite poor at this operation, and I believe my advice will go a long way toward keeping you safe.
I'd love to hear what you think of the morph. Did it seem to address your main concerns? I could modify the morph to your taste if you wish.
Your nose 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. 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.
In your case in particular, you need to find a surgeon who understands all of the issues I mentioned, and how they fit together, and who can actually accomplish them in surgery.
