I've done plenty of Star Wars stuff, so you'll see quite a few of my sculpts in the line-up. (for better or worse) it's an honor to sculpt a character like Obi-Wan Kenobi that's just so iconic and feels so much like classic Star Wars.
Ross Perot ears! HAHAH! Yeah, Guinness has big ears, but I wouldn't doubt I got the proportion off. Something I tend to run into is the neck post kind of dictates how deep I can sculpt a cranium, and sometimes that throws off the 3/4...but I'm coming up with excuses
