How David Hobby created a his 'coming into a shaft of light' look

I just purchased the book 'The Hot Shoe Diaries' by Joe McNally and after browsing it for a little time somewhere there was a mention of stobists blog, a blog about learning how to use off camera flash. McNally apparently reads it too. So I checked my links in the right hand side of the wfrblog under 'BLOGS I READ' and saw a new entry 'Variations on a Two-Light Theme, Pt.2'. Reading David Hobby's entry I was interested in trying to re-create his lighting. Especially when I looked at another example by photographer Peter Yang (here).

So here is my self portrait version . . .

If you read how David Hobby created a his 'coming into a shaft of light' look, what I did was mount my SB900 flash off camera on a manfrotto light stand about two feet, and above, my face. Held up a piece of black card with my left hand acting as a gobo (a card that blocks light) I also had my D300 on a tripod with my (eBay) Phottix Cleon Wireless Remote Control and Nikon 105mm f/2.8 lens on auto focus. I really want to master off camera strobes, they give you such great lighting possibilities.
