You could try pushing the B&W file a little further. The highlights/midtones are a bit muddy, which is something you can totally avoid when you're in B&W since there's no risk of destroying any colors... you just approach white. As it is now, the image, to me, almost feels brown (though clearly it isn't) rather than B&W. I've seen this in my own images at certain, intermediate processing stages.
