Since I'm also interested in the other mystery of this puzzle: what is the relation between white rabbit and coin artist?, I have in mind some questions:

- There's a diagonal line at the phoenix wing, which seems to be drawn on purpose. To me it looks like the move of the waffle ( inverted knight ), also named phoenix in the shogi chess. The white rabbit instruction is to turn the picture according to that line.

- The WR always says time is short, he is late, for a very important date. What date is that?

- There's a website called 17leaves.com which at first the content looks like about yoga and spiritual stuffs. But if you investigate more in the blog, the time of events implied in it will point to an account named StephenMorse. This account is the first one who mention about using leet (1337/1347) to decode. And there's also an account named StephenM347 on bitcoin stack exchange. Is it a coincidence or does he have some relation to the cr347or?
