Mine, like this one, is going to be based off the Miraculous Metal, a symbol heavily worn among Catholics. The metal is based off of an apparition of Mary that occurred in 1830 when she was seen wearing an ivory gown with a blue mantle and a white veil. She stood with her arms out like she is above but had light radiating down from them. She was also stepping on the head of a serpent. The blue used above is waay too bright and overall I don't really like how the tattoo is done, but you get the idea.
In the one above and below I really like the radiating lines behind her. Mine's gonna be all done in color but I do love the clouds in the one above. I like how the one below doesn't used black lines to outline the radiating parts; could do without the stars though. I also really like the roses at the bottom of it. I want mine to be a full-body image, not cut off like these, and I want the serpent to be seen at her feet. Between the roses at her feet and the radiating lines above and behind her, I want the overall tattoo to be in a oval shape with Mary in the center.
These last two are just gorgeous. Not really at all what I'm going for, but they're extremely well done and I had to share them.
