I'm not sure what a "fine art portrait" is.  You'd need to post an example.

Any of your images could be 'fine art' if you want to big yourself up express your professionalism. As the artist, if you define them as 'fine art', then that's what they are. Apparently.

Here's what Wiki says about it;

I'd say the style of most portraits on this site http://1x.com/photos/portrait .

So would portraits like this sell at macro agencies?

I had the same question, so upon examination and a cursory investigation, I came to the conclusion that there isn't enough of a market in stock (whether micro, macro, or RM) to make portaits worthwhile.  I'm talking here about actual, traditional portraiture.  The stock buyers seem to want images that are much more commercial and have a commercial application.  I realize that this encompasses a very broad range of material (thank God), but not portraiture.  Your experience, of course, might be different.

Yeah, and then there's the question of which agencies to UL to. I'm sure as hell not paying Getty 50$/UL (if I even got accepted), nor am I willing to wait for months for them just to review my initial 12, I don't have a clue about Corbis (I just heard they sell a lot less than Getty) and Alamy isn't really a macro agency anyway (and I just hate keywording images there, into 3 sections, in order of relevance etc, it's even a lot worse than at IS). So if I really think about it, I don't even know where I should try to sell those portraits. Is it even worth splitting my attention...I mean, I'll shoot those portraits anyway, but all the hassle with the agencies, I'm not sure about that.
