Aww, thanks for hunting this Chris. It's been one of my all time top pet projects and I've worked on it on and off for years (started it back in 2012!). Other than being a little love-letter to the Star Wars I grew up with, it's also a really interesting creative challenge. What happens when you remove the outline and shape of a character and force it into the same restricted canvas? I learned a ton doing these, not just about lighting and textures but also about how to focus and frame a concept. They're all up on this neat little site on http://appiconwars.com
