Swimsuit model alien (or whatever, most likely not a human), her pose says that she's pretty and she knows it (nice legs!).
Perhaps she's actually a professional of whatever the job the marine environment provides (diver, surfer, lifeguard, biologist, etc.) who just wanna look pretty for the picture.
Her expression looks hard, while professional high fashion models are often not smiling but I think this is different. Coupled with the wild crashing sea behind her, I think it strengthen her toughness and make impression of a person who stays calm in danger.
LOL I don't have good picture of my characters.
