I think that is a interesting topic, i did once a test as FBI profiler, you could test yourself if you can read emotions etc.... and guess what the character is like, i dont remember if i scored well... but you can try too... you can post your own pictures too and others read you...

I think despite looking serious into the camera and trying to look intimidating, i think i see a underlying "weakness", "insecurity", "shyness", "fear"
