I tried that out... and it really does just consider the symmetry and ratios of your face... so I thought it'd turn out horrible because I'm not symmetrical, but here's what I got:
You are an 8.81/10
Here's why:
-Your face has poor horizontal symmetry
-The ratio of your nose length to ear length is nearly ideal
-Compared to your eye width your innerocular distance is nearly ideal
-The ratio of your face width to nose width is nearly ideal
-Your face is too narrow/long
-The ratio of mouth width to nose width is nearly ideal
...so aside from my poor symmetry, it seems like I've actually got a fairly well measured out face?
haha -- ah- I'm only posting this because I'm shocked. It's kind of funny, actually. XD
