BB: Very impressive work! I'll test your eyes with Antonia this weekend. My gut feeling is that your irises are probably a bit on the small side when compared to real eyes, but I might be wrong. My only real concern is that if we make the eyes bigger, then we need to change the center of rotation for them. That's fine for Antonia since we're planning to simply replace the existing eyes with your version. But if you're thinking about making eye-replacement props for other figures, you'd have to make sure your eyeballs have the same size as theirs, so the relative iris-size needs to be whatever is appropriate at that size.

-- I'm not mad at you, just Westphalian.
