Black and white

Just before sunset I arrived at a location I visite quite often, because it's a beautiful place and my sister and her friend Peter live nearby.
It turned out I was too late. A lady told me that moments before I arrived the sky was beautiful, all striped with orange sunbeams. All I saw was grey clouds, with just a tiny bit of orange left. I made some pictures anyway.
When I saw this photo on my screen I decided to turn it into black and white for a change, something I haven't much experience with. When I did, the clouds suddenly became much more spectacular.
Please let me know what you think of it, so I can improve on the black and white bit.
