Louis was my preferred character whenever I'd play L4D, so naturally I had to do a custom figure of him. He's a pretty simple character design, but was a somewhat difficult project to find parts for.
There's a really limited number of non-white, non-male head sculpts available for customizing. There have been some excellent version of Louis made using various Mace Windu (Samuel L. Jackson) heads, but I wanted to go a different route to differentiate my take on the character. I think my patience in finding the right head paid off as the likeness for Louis's game model is pretty close in my opinion.
