This is the start of my first tattoo... still healing. Still about four hours of shading left to go on it. I had my two sons birth footprints incorporated in to the surface of the moon... and the trunk of the tree will be a symbol of my wife and I.
I normally don't like tree tattoos but your outline so far looks awesome! I like the idea of the footprints on the moon. This tat would look good in black and gray but i personally think it would look better in color. Good job.
