Reversed chin angle? (Photos)

hello, it's been 6months post op after my sliding chin genioplasty. my chin moved forward 6mm angled. i'm kinda satisfied with the result except that my chin moved downward a little bit (approx. 2mm) and it's a little bit asymmetrical as well. its really disappointing in 3/4 view. i would appreciate to let me know what are my options to fix the problems. would chin grinding down make result??? or another chin sliding required??? now i more concern about my frontal rather than the profile.
