Lovely flowers! The image ia super crisp and detailed and the macros are done very good! I like that effect of the light circles with the halo! How do you achieve such an effect?

The proverb made me look at the petals like the cusps of an heart valve - the flower in the first image does look a bit like the tricuspid :) 
This is a nice proverb - I remember looking at an old heart in a dissection for the first time and thinking to myself - it was a person that loved and was loved by others, there is more to a person than this seemingly old and sick heart - it's an important concept for a med student - one that can keep us respectful even after spending hundreds of hours at the dissection room.
