I am absolutely in love with this phases of the moon tattoo. I'm not so sure I like the placement, but the concept is beautiful. It's such a minimalist tattoo, but is still noticed and easily appreciated.
A very well detailed Triangle Glyph Tattoo. You can see that the pink flower is fully colored within the glyph triangle symbol as it slowly branches out into the less colored parts of the flower as the colors are only concentrated in the center.
