Honestly, the whole face one is ill, but make it a little more less evil and twisted up and more human-like and your in business...
The eye's one, well that one really does look like it could be anyone, if it was intended to be Tech, if not then cool... But it would be absolutely stupid to place on a shirt!!! Who'd buy it, and why make his image as wild as that. Take it down a few notches and calm him face down to a more mellow Tech, and that'll look more like him!
