That's a really nice shot Ian. The lighting and background set-up makes me think it was done by the Anti-Ian, a strange imposter from another universe. I love the contrast with your darker shots, and I do think this would work very well shown alongside some of those pieces. I love the tight vertical feel too, and if I have time, and the model and you are OK with it, I'd like to work this up into a painting sometime.
Every now and then, I intentionally do something outside my normal range. It helps to know (or show?) that I can do it, I suppose. In addition, in this case, this is the sort of thing the model (client) wanted for her portfolio.
I have to say, though... I really enjoy the bright high-key stuff. There's something fun about a photo that's over the top in one direction, and where the contrast is minimized. I guess I just like extremes.
