Heya Jim, these are good!
(Well, there would not be a Jim-flower-photo that is NOT good, now would there?)
I like the harsh light, it goes well with the all black(ened?) background!!! And I love the velvet character of the petals in the last. Reminds me of a tulip photo which was among the first I ever posted here on TPF and someone said, normally one would not like to see clear reflections on flowers, but on that one it worked. That photo, however, has LOOOONG been taken off the server ...
