Interesting & unique composition.
Guess my only critique on this, is the main focal point of the 1ml beaker is a bit too dead center and falls outside the sweet spots in the rule of thirds. The purple shadows & reflections do add to the mood.
A well-deserved ((7))
I personally would have like to have seen the main subject more off center, probably to the right. I do really like the colors and every thing is lit well though.
