the lip it self looks natrual (and that is what I think you would like to express?) but like others mentioned the upper lip looks a bit like it is folded inside, what you might have done as well was ensmallen the lower lip to compensate the upper one.
Tip: try to make tose gaps at both sides of the lips a bit larger that always makes a nice smile.4/5
