Haha yeah, I can totally understand that. I've never been comfortable in front of a camera.. However it's mostly due to my "Swenglish".
I don't mind showing my face or whatever.. It's the talking part of it. - To speak in English... That's my biggest issue... And that is why I write in English and talk in Swedish. :P
I say go for it man, I'm sure your English is excellent, even with an accent :D
