it's always interesting to see something is unconventional and as you mention yourself, flash-light and flowers is rarely the approach.
You have good control of the whiteness of the light shows off the flowers differently than what is usually the case. Less warming and more white than what the sun or even an overcast day normally produces.
Personally, I like the second one best because of the subtleties. At first you don't really notice the green leaves in the background - they sort of appear in your peripheral vision after a few seconds. It looks like a portrait shot of a plant.
The fact that you managed to avoid much of any shadow inside the flower is quite an accomplishment I think. The light is pleasingly soft without losing any essential details.
In the second one, I think yo have a difficult model, so to speak...lol. What might be equivalent to a bad hair day, sort of...lol. The whiteness of the spikes conspire to make the very top look almost overexposed, although I'm sure you have scrutinized that yourself.
The natural brownish color of the bulbs (are they baby-cones?) doesn't come across so well - in my taste - under the white light. Perhaps a tungsten combined with a behind-the-plant "hairlight" would do brown more justice?
I think there is potential in the "plants and studio portraits" approach and the second one is a good proponent of that technique!
