A tattoo that fits perfectly

things with wings have that bend

It's anatomically correct when it's compared to this type of tattoo which is more common:

Now whenever the person lifts their arms the wings flap vs the constantly folded wings tattoo.

It's better, but wings that size would get the tattoo owner nowhere

I think people get this tattoo mostly for symbolic reasons. Having wings= being as free as a bird. I don't really know.

Don't get me wrong, they're cool af but I wouldn't call them anatomically correct.
