First of all, congratulations! That was a good-length spot, and you got to talk about a lot of things, which is always great.
A few critiques you might want to consider for your next interview. I thought you had some really good looking images, and your story about how you got started in photography was touching. I really wish you started your interview with these. No offence, but I didn't know who you were, and when the interview began with you talking right away about things like getting on the ground, I wasn't really engaged. If I was watching it live, I may have switched the channel. Until I started seeing your pictures, that is. It's like listening to a guy getting on stage...you don't take him seriously until he starts singing. If we saw the images and your intro up front, it'd have hooked the viewers better IMO.
On the content itself, you had some really interesting and useful tips (reversing the lens for macro, capturing sun at small apertures, etc.), but they seemed random. It was like we had a chat at a coffee shop, where you talked about miscellaneous things to a fellow photographer rather than to a beginner. Which is great, but not something that'd work on a TV spot IMO.
Which brings me to the other aspect, which is that I didn't get who this was targeted at. I'd think by default you'd tailor it to a novice, with the hope that budding/aspiring photographers would listen to you and be inspired to take up photography. But you were using terms like the viewers already knew the fundamentals, and you didn't offer the basic advice on picking a camera, lenses, etc. Like I said, it sounded more like a collection of thoughts rather than a scripted/structured interview with a goal. I'd have worked through the script more. Like you said, may be the editing messed up the flow, but I'm only commenting on what I saw.
Bottom line, great looking images and interesting interview, which is why I'm taking the time to give detailed feedback. Wish you many, many more interviews! Please do post back.
