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.
I did enjoy the show, I did. It was actually funny to watch, nad i really loved the parts with Bilbo. But all the changes are clearly meant to please those who like hyperkinetic or epic movies and "cool" characters. The point is that in the Hobbit there are only two "cool" characters: Gandalf (a wizard) and Bard (a man). Even the main character isn't cool: he's a hobbit, an example of "courage under pressure", but not showy or epic or cool. The dwarves? Neither. They're greedy, fussy, niggard, sometimes coward, their leader is terribly haughty, ever ready to lay the blame on someone else and lacking of a great deal of sense. I can overlook minor changes (the lack of hoods for the dwarves, the timing of their arrival in Bag End, even their short beards) but the fact is that, in the novel, the dwarves are the comic relief, all of them (look at the original introduction of Thorin in the book - crushed under the combined weight of four dwarves, one of them exceedingly fat). Peter Jackson, in order to turn this sort of fairy-story into an epic movie, made them appear as heroic warriors, so he had to create another form of comic relief, and chose the poor Radagast as the butt of the joke. That's what I don't like.
I respect your opinion, but I peronally enjoy the fact that Peter Jackson has decided to make the dwarves great warriors, and if you look at other movie and cartoon dwarves, you'll see that's actually going against the grain. Most dwarves in the entertainment industry are used for comic relief, they're usually grouchy and bumbling and ridiculous, I really like that Peter Jackson has decided to give dwarves some respect, even if it's not like that in the books. And I actually like it when a movie doesn't follow the book exactly, I think that directors should feel free to stretch the story and explore and interpret it in the way they choose, even if that doesn't always end well. Also in the original Hobbit a lot of the dwarves didn't really (In my opinion at least) have very distinct personalities, and Peter Jackson has used that as a blank slate to add his own.
