You'll receive a variety of answers and opinions, but my recommendation (with the very limited information available in your question and photos) is to proceed with extreme care and caution because of your existing natural beauty. Only if you MUST have a change and/or improvement should you consider surgery. In general, a smaller nose visually enlarges the eyes but from front view, straightening the top of your nose (which already looks very nice) is complicated surgery and will not change the eyes at all. The primary asymmetry I see is your upper eyelids. The one on your left in photos (opposite side from piercing) seems a bit lower than the one on your right (the side of the piercing). This can be corrected but may introduce additional asymmetry of your upper lid width. It's a very delicate procedure to be attempted only by experts, and will not produce perfect symmetry. Perfect symmetry is an unrealistic expectation and not necessary for beauty. You are very attractive by any standard, ENJOY.
