Guybrush is my favourite videogame character of all time, he is the hero of the Monkey Island saga.
I hope you enjoy it!
Step 1: The Sprite
I used it as a guide.
Step 2: Draw It in a LEGO CAD
I drew my LEGO model using one of the CADs available on Linux, which is the operating system I use.
For the record, I used leocad (http://www.leocad.org).
Step 3: Render It Nicely
I was very happy with it!
