Great collection! I considered collecting the Master Builders, but decided it would just cost too much - so I limited myself to just the main characters. I've studied your pics and couldn't see them in there - do you have the Magician, Artist, Circus Clown or Yeti? And Lord Business himself seems to be missing.
The Lord Business is near Metalbeard on the back ^^ (behind the statue of Liberty)... It's hard to take all of them properly on a base plate xD! I need to see how I can modify my aperture on my camera, so I can make it all sharp too ^^
I still have the "Hearty crew" Legos to collect, and yes

the magicians, artist and clown are missing :X! Is the Yeti a master builder? I can't remember where he appears in the movie!
However there are a few I cannot identify and I believe they had been made for the movie, there is a guy similar to the LumberJack Lego, but he's different, and the logo on the cap seems to be different too, there is also some sort of traffic officer next to him!
All of the cowboys in the Dog room doesn't seem to exist either, couldn't find any right torsos...
It has been more expensive than I anticipated to be fair xD But BrickLink is a gold mine! Got everything much cheaper than you can find on ebay!
And obviously the Michaelangelo... I'm sure i can custom the sort of cape, but yeah he has distinct legs and torso...
