Well, in both of my downloads my face isn't shown... That doesn't mean I have something to hide or whatever, it just means that I am quite shy and I always try not to appear a lot on the internet. But now that I've read what Patrick has written, I'll consider to take it into account in future downloads, it's actually a good point.
Venom, I advise you to write an outline of your project before you start to record, it will help you a lot! And also try to find someone who can help you, someone behind the camera that will make sure the angle and zoom are OK. Record more than one take, find an app that will enable you to edit the raw footage properly (I personally love FCPX, but it is quite expensive... iMovie is great if you hace a mac) and make it look quite natural, don't apply lots of effects and filters, it distracts a lot. Finally, be honest! Don't record a trick and heavily edit it in order to hide the sleight of hand you may use just to make it look better or more decieving.
I hope this can help you a bit at least
