Very nice Danny.
I got mine recently and although not really "geeking" wether the light is any different to other SB's I do LOVE the new easy to use interface. Worth the price of admission to me as HATE messing with a flash when should be composing and setting camera.
I agree... the 800 or maybe the 600 would have done the same or maybe even better. No disrespect to anyone but I believe the 900 is overrated. Outside the 800 the next step up would be a Qflash or any other portable studio strobes.
Your model is stunning, and you've used some of the best gear money can buy, Danny. It's a good result, but you'll do much better if you take the flash off-camera. The sb900 in the hotshoe can be your commander. Put the other in remote mode off to the side.
