#1 A good tattoo conveys a message. I believe that the purpose of a tattoo is to reveal an important part of yourself. A good tattoo embodies meaning and speaks about your uniqueness.
A bad tattoo is a patch of fancy artwork you get inked in your skin out of impulsiveness.
#2 A good tattoo gets done on the bodily axis of symmetry. That axis is a vertical line which divides the body into two equal parts (disregarding the change in perspective). I think it’s best to have a tattoo done anywhere along that axis because otherwise the symmetry of the body would be visually affected. I mean that since the human body is symmetrical – we have two legs, two arms and two eyes, etc. each on both sides of the axis, and a head, a nose and a navel, etc. on the very axis – getting a tattoo done only on one side of the axis would create a visual unbalance. Symmetry is important because it creates holistic beauty.
#3 A good tattoo is symmetrical. A symmetrical tattoo done on a symmetrical spot would look like it’s part of your body as it would add to the symmetry of the body without disrupting it visually.
A good symmetric tattoo on a symmetric spot is likely to be regarded as an indivisible part of the your body; a good or bad tattoo on a random place exists in distracting isolation and visually undermines the aesthetics of the human body. The size and colour of the tattoo are irrelevant.
Last, if you cannot think of an art work that embodies who you truly are and why you are unique, I strongly suggest you postpone the ink and re-discover yourself first.
I don’t have tattoo and I don’t intend on having one. Yet, I believe that my views on good tattoos will help you stand out from the crowd.
