I’m planning a meaningful half-sleeve tattoo centered on the Aquarius goddess to represent my identity as pansexual and non-binary. I want to include symbols for my children (a lion and unicorn), a tribute to my brother who shares my birthday, and Pisces elements honoring someone who helped me awaken. I’d love your help designing something flowing, symbolic, and in black and gray that tells this story.
