Over turned nose as a result of closes rhinoplasty, can it go back to its original position if it's "released"?

Based upon the few posted photos I think your result appears very acceptable. But ONLY IN PERSON evaluations allow a better understanding of the issues you are unhappy about./// 

The columella strut graft and suture techniques rotated and shortened your nose.  Additionally, removing the bump and creating a curve to the nasal dorsum adds to the rotated/shortened appearance of the nose.  Simply undoing these maneuvers will not reverse the results, but they will be part of the process in allowing the nose to be lengthened.   Cartilage grafts are need to reposition the tip to create a longer appearance.  In some cases when there is excessive overrotation, the presence of scar tissue and skin contraction could limit how long a nose can be made.  From the photos you show I would expect that you could get a longer nose if you would like.  The use of computer imaging can be beneficial in your circumstance to ensure that the surgeon's and your expectation are aligned appropriately.    

The main issue regarding lengthening any nose is the skin of the nose.  If it becomes too contracted/scarred, it will be difficult to lengthen it significantly.  You need to let enough healing time pass to avoid operating in an inflamed surgical field but not so long that scar tissue sets in which can actually contract more and cause further shortening, depending on the techniques performed at the time of surgery.
