lol, the first time it didn't even get most of my face >.< (I clicked, 'take picture'', the computer lags, and then it gets the left side of my head and a lot of the wall & a picture on the wall... and it accepted it, so I was all like, 'why not? X3')... interestingly that produced a 58% match, which was a higher number than my other two matches at 57% (3rd try, had monitor glare on my glasses X3) and 56% (second try, it missed my mouth because I was too close and didn't realize it would not resize the selection box thingy).
Interestly, I got mixed breeds for every try after the first (that doesn't count, because it was the wall >.< + a picture & frame), matching my rather mixed genetic heritage.
