LOL, are you the person who was asking about removing the apprature blades from a lens in the forum last week?! Hahaha, you actually DID it! Very cool, I've always wondered how these things worked. But I warned you, the lens is ruined now. :)
I guess this shot used deep DOF. It is hard to tell because there really isn't much in the way of background or foreground. The subject itself is not presented in a way I find compelling. It does demonstrate in a way how deep DOF is achieved so I'm not sure why you didn't just go out and take a shot of something using deep DOF to show off the advantages of the technique.
