Not sure if this was intended at me as well, so sorry if I offended you. I did my stint with selective colour, I think we've all done it... for me, I've just gone off it, generally speaking. I think there are times however when it does work however.
Correct me if I'm wrong, but when you're using selective colour as a processing to an image, you're drawing attention to that area specifically. So you want to make sure that area is a definite area of interest. My thinking was that if you're wanting to draw the viewer to that area of interest, then it should be in focus. The first thing I saw was OOF hands, which in my opinion, takes away from the original image. I'm sure that without this, it's a cracker image, well thought out and creative. But I can't get past the OOF hands. And that's why I think it doesn't work. No offence intended.
As an aside, I have a big ar$e canvas on my lounge wall of a fishing village in B&W with a big red lobster boat big as the almighty... I liked it at the time I did it (about 8 years ago), but cringe when I see it now. The husband and everyone else loves it though... *rolls eyes* lol...
