Nice work. I wonder what PJ had in mind when he accepted an almost shaven dwarf and one with a goatee who look so young ( they were 82 and 77 years old, after all) and I have some misgiving about the look of all the dwarves in the movie, but you did a good job.
They were young, yes, for dwarvish standards, but these two look a bit too young... and a dwarf belonging to the Longbeards clan cannot be shaven, come on. BTW, both Fili and Kili had blond hair. There were other possible ways to distinguish them, combing their hair and beard in different patterns, for example.
It was a creative choice by the director, and it's a brilliant movie (at least in my opinion) and the way I see it you can either let this small thing bother you, or you can sit back and just enjoy the show.
Nice work
