Another new headshot of which I'm particularly fond isn't mine -- it's a new one for Marc Hustvedt -- who was a fellow Austin actor who's now become a successfully working LA actor. This pict is by photog Dennis Apergis, and is a great dual-purpose (at least) commercial and comedic headshot (it almost screams, "Put me on 'The Office'!").
Networking is awesome, but good headshots open doors when you're not there in person. (And it's necessary for you to have the professional and acting skills to follow through.)
