I like the second one because it seems to bring the viewer in a little closer, more into the scene.
I wasn't sure if I liked the sign included or not; it isn't particularly interesting itself but yet it seems to balance the statues and the people. I don't think it's really a distraction, it seems part of the scene. I think I like it in better than out being in B&W where I think you notice the pattern of the shapes.
Removing the grain makes it seem more stark and artificial, I'd leave well enough alone.
