Hi i have been like 5 to 6 years trying to find out what i want to tattoo and i have the idea now

is a portrait of my Wife and maybe then a Portrait of my daughter, both of them are great thing that happen in my life.

my wife have diabetes and we are toghter working in out so i want a portrait of her because she is an inspiration to me the size of the tatto maybe like the standard size of a photo 4X6.
