I think that it's good that you haven't posted a comparison shot, because 99 times out of 100 I wouldn't choose selective colour as my favourite. You also chose a very difficult subject to try to salvage all the colour tones from. Having said that, this one seems a bit different than normal because there's still a little colour in the background instead of being completely b&w.
I think if I saw this image in b&w I'd love it.
