My angel is my 9th and biggest tattoo to date...and strangely enough, the first one I ever wanted! It came together in three seperate sessions. The angel herself was done first by Brad at MacKenzie's in Carmel NY. I went back to him a month later and had the sun/moon and large star added...then the star looked too big! So the third sitting was with Cuda at Iron Butterfly in Mahopac NY - I had him add the three smaller stars, he also added an angel boob and refined the face a bit!
I really like the idea of a space background to fill in the background. I would keep it subtle so it doesn't detract from the angel, sun/moon, and big stars.
