A lip lift is very cost effective in terms of facial improvement and you would benefit from it. A lip lift does 4 things: shortens the distance between your nose and upper lip, increases the mucosa of the upper lip, increases the incisor show and pulls up the corners.

According to these photos, you do have slightly longer upper lip, based on aesthetic standard measurements. However, your lip is full, nicely shaped and projected. I do not see specific reason for lift. In person consultation with an experienced board certified plastic surgeon with good reputation in facial surgery is recommended. Good luck.
