Sisters love heart bird tattoo

This is what a business in Australia was looking for in their tattoo design

We would like a sisters tattoo, same but slightly different for each sister. See attached image. (But without the flying bird) We would like something minimalistic (love heart dotted line with 4 birds sitting on that line. We would like 3 birds just outlined, not coloured in and 1 bird highlighted in each tattoo but not completely coloured black but more like a light shadow to highlight which sister owns what tattoo (so sister 1 has the first bird subtly highlighted, sister 2 has the second bird highlighted and so on)
We would love the tattoo as small as possible (maybe 2 or 3cm, the smaller the better? ) With very small minimalistic birds if possible) Read more
