Very Cool!
However, I notice when you use the Hexagram as a Key, Saturn does not line up, everything else does. As shown above, and also in a post i did a few days ago. The top point does line up with Daath(Sirius, Sothis, the Abyss, no number) which shares the same God aspect as Saturn. Daath - the hidden Sephira of knowledge. Is Emanated after Binah(Saturn).
If you were to take the Hex Key and slide it up towards the Supernal Triangle to Physically include Saturn.
These would be the correspondences:
Top: The Primordial Point, Top Left: Saturn, Top Right: The Sphere of the Zodiac. <-- Supernal Triad. Center: Daath, Bottom left: Mars, Bottom Right: Jupiter, Bottom point: The Sun.
Here you begin with Atziluth, pass through Briah, and descend part way into Yetzirah. As opposed to the key in the center of the Tree, which only includes the six Sephiroth of Yetzirah.
Also, if you look at the Hexagram as being divided into 3 columns as the Tree. Then the left points represent Severity(Form), the middle Consciousness, or equilibrium(force and form), and Mercy on the right(Force).
These are just a few observations i made,
Cheers
