it seems that the B&W version could use a little bit more contrast boost.
Thanks for the flower basket. But I disagree with what you said. Contract boost would take a toll of details. Particularly with regard to the first one, the foreground details are important. The texture of the snow field in the rest of the pictures except the second one requires careful balance of contract. Only the second one may tolerate some contrast boost, which I did make, as you may see in the pretty dark foreground.
