I like the fact that people have such reverence for Biblical figures that they'll get tats of them, but turn around and don't even capitalize their names. The knife sticking out of Mary's head is a nice touch as well.
I think the figures look great. Is the heart part of the tat, or was it already there when you started? It's the only part of the tat I can't quite figure out the point of. But I like the tat -the whole thing looks really good.
