This is heart - shaped tattoo on shoulder. Tattoo has no outlines, but has many ornaments inside. You can see various types of details - floral details, lines, circles, dots. Maybe include kids' names within design somehow.
Enso or the zen circle, though an old theme, is becoming a popular choice of tattoo now. The swish of the circle looks crisp, graceful, and elegant. The incomplete circle represents the universe. It also stands for inner strength and enlightenment.
