Thank you!
Fons: I used three flashes, 2 with soft boxes. Thought about continuous light but decided to opt for flash. Unfortunately I was not patient enough to get really soft light so I may switch to continuous light next time. BTW: I used a polariser to intensify the colours.
I also shot with a white background to convert to monochrome:
#1

#2

#3

The last one differently processed:
#4

And a different processing for the ones with black background:
#5

#6

And grey background:
#7

#8

What do you think what works and what does not?
