Rhinoplasty: 16 days post-op piggy nose. (Photos)

Yes, still considering your shape will improve it seems clear your dorsum is over resected and you developed or will develope saddle nose deformity, which requires a very good expert in revisions to be fixed.Additionally your tip is over rotated, need addressing too.You'll have to wait a few months, maybe 1 year, to full settlement and then undergo revision with a good specialist.If you wish better grounded opinion please do post or send privately well lit, focused and standard images: frontal, both lateral and both oblique views, also underneath the nostrils.
Feel free to request any additional information from me.

Dear MariL028,It is still very early in your healing process to tell how your nose will turn out. There is still a lot of swelling 16 days post op. 
It can take 6-12 months to fully heal from a rhinoplasty so patience is key.Best regards,Nima Shemirani

You are very early in your recovery period and the nose is expected to be quite swollen at this point.The majority of the swelling will resolve in 3-6 months, and will continue to resolve as your nose heals for up to 1-2 years. You have not reached your final shape as the nose will continue to heal and reduce in size for up to a year. Once it does reach its final shape you may be more pleased with the appearance of your nose.

Your up close photos reveal a less distracting and more feminine nasal profile, and your nostrils appear symmetrical on front view. You are still quite swollen this early after surgery, and your nasal tip may drop a few millimeters as you heal. Worrying never leads to anything good - If you need reassurance, consider visiting another rhinoplasty specialist for a second opinion. Hope this helps! Dr Joseph

From the pictures you've provided, I see no significant issues.  The swelling will begin to subside, and the tip will become more defined.  Be patient and keep your follow-up appointments.
