It's Anna's eyes - they're too close together. And Elsa's eyes are pointing in different directions. Like her left eye (our right side) wouldn't be looking that far right because of the angle of her face. But it's not too bad, it's really just Anna.Trust me though, these things are difficult to spot especially if you're the one editing. I've had this problem many times and I've had to ask a lot of people what's wrong with my photo. Sometimes if you sleep on it and look at the photo with a fresh pair of eyes, it's easier to spot.BUT DON'T GET ME WRONG, THIS PHOTO MANIP IS AMAZING. GOOD JOB
