The character Big Daddy from the video game Bioshock was rendered in LEGO bricks by Pate-keetongu. I love his explanation of the build.
There is a lot of SNOT in the torso. Okay, there is lot of it everywhere. But I'm happy with the shapes of the torso, the hunchback look and the suture between the head and the upper torso.
The arms were probably easiest parts to build, save the simple canisters on the back. Ball joint are just so much easier to play with than the clicky joints.
