Oh my goodness. I want a "joy" tattoo so badly ever since last summer. I love this font. I'm not sure about the placement, but it's pretty cool. Plus, this would be a meaningful tattoo for me, not just a frivolous thing.
Not sure how I feel about the branches of the tree.If they mirrored the roots in style and spread up the hand, rather than being all clumped up in the palm, I'd be in love with this tattoo. Love the idea/placement!
