Underbite Veneers; how can I improve my smile? (Photos)

I have an underbite and i think it's not moderate nor minor ... i was thinking about jaw surgery but then i changed my mind because all the people around me even a surgeon i know said my face looks just fine ... the thing is i don't care about my bit that much all what i care of is my smile so am wondering how can i improve my smile ? is it possible by veneers and porcelain ... now am not saying i wanna fix it i just want to improve my smile
