First off, I couldn't find anything specifically nit-picky to point out. So kudos to you for that. :] I wish I could say I'd read his work, or at least heard of him, but that would be a lie. I haven't heard of him before, but from reading this he sounds like a cool guy. The whole thing flowed very well, it was really interesting and it definitely kept my attention and made me want to keep reading. You seem like you've got a lot of talent. I almost wish I could find something wrong with this so I could actually give you some helpful feedback, rather then just telling you I like it. I'll probably look this guy up now. (thank-you google!)
On a side note, how awesome is it that you got to interview one of your favorite authors, let alone a writer who very, very rarely does interviews? Most people don't get a chance like that, so it must have been cool for you as a writer to talk to someone who really knows his stuff.
If you'd like me to read over the second part, just let me know.
