Marcus Manis- Abstract Dark Wing Nail Art

Marcus did this nail art so long ago but I completely forgot to post it up, sorry! So don't go thinking I got my claws back because i haven't *sob*

We didn't really know what to call this. It started as a sort of butterfly wing type pattern but I am not really sure now LOL!
But whatever it is I love it!

He used OPI Russian Navy as the base colour than added the design using acrylic paint including some yummy metallic silver paint.

What do you think of this design and what would you call it?
