I'm looking for a matching tattoo design (for a couple or two people) that is unisex and complementary — meaning each person has half the design and together they form a complete image. I want the tattoo to be in outline (line art) style, minimal but stylish and trendy. The design should be inspired by one or a mix of the following elements: Water / Sea, Puzzle (symbol of connection), Music, Fire, Love — preferably a blend of more than one of these. I'm open to seeing multiple variations: Some in vertical orientation. Some in horizontal orientation. One version where the sea is the dominant theme. Another where music is more dominant. And one where love and fire are combined like the other themes. The final look should be elegant, creative, and suitable for both men and women.
