After my 3rd child was born last summer I wanted to get a tattoo that represents all 3 of my kids. I decided to have their footprints put on my back along with their names. I wanted the names of my sons in blue and my daughter's name in pink. I took each child's original footprint on the day they were born to the tattoo shop and they put it on my back. I love how each one is different based on their distinctive features.
this is done alot but oh well so is alot of tats out there I really like how yours is done. I think you should post a closer pic though to really show the detail better
