Golden spider lily in the night

In front of my house entrance, a symbolic tree of apricot exists and at the root a cluster of Golden spider lily are now full bloom.
 I have tried to get images with four different lighting.
1)Single strovo through white screen
2)1)+black paper as background
3)1)+one more strobo at background
4)almost same but different angle
Have a good night!
