These are so beautiful.. but it is too similar to what you can find on the internet for metatron's cube. Can you go to this link.. and see more narrowed direction http://childrenofthesun.org/i-am-avatar-logo/
I like the entry #49 a lot.. it brings in the A and the V.. for Avatar... It makes me think that maybe I can let go of metatron's pattern. Maybe change the coloring on this one.. and the inside patterns. Different variations of this theme. It is very close. Thank you for your intuition.
If you see inside the Metatron's Cube... there is an "A" that can be pulled out through color. (See the type of "A" in the website example... http://childrenofthesun.org/i-am-avatar-logo/
That might look really cool.. to have the "A" coming out from the Metatron's Cube
