I like it. My own little journey through Divine Mirrors ended in a story of just about a thousand words. 

There were some things I thought were a bit confusing:

• Under the Egg header it talks about adding points but where and when to add them exactly is only explained after you've rolled more dice for the creatures looks and only then does it explain it. That was a bit confusing.
• Under Yearling there is a small mistake - How has the yearling has grown
• Under the Divine Beast header it talks about how the beast has reached full maturity and then it says the same under Culmination

Overall its also basically impossible to get the opposite result after you got 2 points in either of the traits and since you chose which one starts with a point already it feels a bit superfluous. For a solo game I'd personally want the option for the story to change direction from the first to the last roll so I wonder if using d8 or d10 might not be better to lessen the impact of the points.
