(I'm prefacing this because upon reading over it a few times, it sounds like I'm talking down to you. I really don't mean to, but I've always had a problem with people thinking I'm being more rude than I intend. It's because they're whiny babies and can't keep their pwecious widdo feewings out of the way for five seconds. You seem smarter than this. Also, I was just using the demo. I do hope that in the version for which people pay a lot of money for your expensive program, you've already taken care of it.)
I find it hard to believe that in 5 releases of this program, no one has corrected this. I've included images since my ability to clearly describe things is severly lacking.
Here is an unfolded representation of a human eye (it's for a program that uses this for both eyes so the mucus membrane is inaccurately on both sides). I'll accept not calling the whites of the eyes "sclera;" giving you the benefit of the doubt that you'd know that, not everybody does.
The next image highlights what you have called the pupil. As everybody has learned in . . . I'll say third grade, but for me it was around first grade or kindergarten, this is the iris.
THIS is the pupil.
Unlike the iris, the color cannot be changed. It is a hole in the center of the iris muscle that allows light to hit the retina. The iris expands and contracts in relation or darkness or brightness (respectively) to allow in enough light so the optic nerve can pick it up but no so much that it burns it out.
Personally, no matter how innovative and fun this program is, I would not pay even $20 to have to see this mistake every time I mess with the eyes (pet peeve, you see. Also I'm really cheap). That being said, CrazyTalk is totes fun. Thanks for all the hard work you've put into it!
