Okay, I am in love with this piece. Spherical flames usually turns out rather... Well, generic but you sure avoided that.
The good stuff first:
I love, and i mean LOVE the swirl in the top. it's so smooth... And it has nice hues! The center also has this tiny spiral to counterweight for the big one in the top, making it look more harmonic. I always loved that kind of Yin/Yang composition.
One bad thing, tho. I don't really think the four-petal flowers *really* fit into this piece, but that is a minor detail.
