It makes you think :)
It's definitely interesting.
During watching it expression "Twisted Circle of Life" came to my mind but I'm not sure if that's exactly what I would like to tell you, to be honest.
I will definitely watch this again somewhere soon to get even more of it.
The concept is very interesting and I think that you have presented nature (even if it's created by other creatures, I would still consider it nature) in this mysterious way life seems to appear to us.
After watching it I feel at least slightly (if not more) overwhelmed by how this -- let's say -- sine curve progresses. From life to death, from death to life, from creature to creatures, from creatures to creatures, from creatures to creature.
What I have found fantastic about it is that it perfectly denies the boundaries between death and birth. Life seems to be as one and it cares not even a little about how we, in our existential way, interpret it.
So, even if I'm completely mistaken by your concept, it provoked me to interpretation and that's -- I believe -- is one of the most beautiful things when it comes to experiencing creations of other people :)
Thank you.
