I prefer the b&w, mainly because the green mark on the statue stands out for me. And the background, because it's not very out of focus is even more distracting in colour than in black and white - for me anyway.
It's a very contrasty shot, so the faces of the men are a little muddled with the background, but perhaps much less so in full size, you could perhaps try to make the background less clear and intrusive in ps - quite a job though.
I feel like it should be a great shot, but something doesn't feel quite right. Perhaps it was just too busy a background for a busy action shot...?
No offence...?...just been staring at it for ages trying to put my finger on what's not quite right...
