I've got to tell you these pictures gave me a good chuckle. I want a candid picture of the photo shoot. I'm imagining your significant other took them for you?
I will second (third,fourth,whatever) the "just shell out the bucks for a proper headcam" comments. Mostly when you try to bodge something with improper parts it's just a pain, barely works, and breaks or fails in some way almost immediately. At least that's my experience. At the very least it looks kinda goofy. Maybe trim down the shield a little?
