I'm more than happy to answer questions, no worries.
For that particular shot (and about 90% of the shots I do) I'm shooting on a Canon Rebel XSI + Canon 50mm 1.4 lens. I'd say I was about a foot and a half away, and I cropped it down to that tight.
I used a flash, bounced off my roof, through a home-made lightbox.
