Stark black tattoos with lots of detail are great for people with an artistic eye. They look great incorporated into a sleeve of cohesive black and white pieces, but also work with colored tattoos. They're a nice middle ground between the classic green-hued ink and bright vibrant designs.
Galactic tattoos are intricate and always unique; no two are alike. The designer has total creative freedom with the shapes and colors, and this specific tat uses an armband design and galaxy fractal. It probably took hours of sitting to fill in all that watercolor-style ink.
