Cover VS Cover: Forgive My Fins and Lost Voices

I have these two different covers for Lost Voices and Forgive my Fins and both are pretty cool so I wanted to show them to you.

 You know what sucks about these two covers? There's no fins!! So that was a huge let down, but other than that I like the first cover more. Mostly because of the makeup and the pose of the model. I like how the girl is smiling in the second one, but nothing other than that.

  I love BOTH these covers!! It's such a hard choice for me. I mean, the first one looks awesome, and I like how the designer did the fin (See? This one doesn't even have FINS on their title and it still has find on their cover) but the second one looks like the mermaid is out to get you. I don't know, Im torn!! I think I'm going to choose the second one...
 
What about you? Which cover would you buy? Have you read these books? How were they?
