Butterfly Wings Nail Art

This is probably my favorite nail art that I've done. I was worried it would be too complicated, but it came out fantastic! 

I have some nail art pens, which made this actually pretty simple, once I had a couple reference images in front of me. When I was looking up some different examples, I just couldn't decide what background color to go with, so I ended up using five different ones! I love the rainbow effect that it made.
