Time to Decide

So I’m ALMOST done with the second Bridesmaid in Paradise book and I’m trying to decide on a cover. The title will be Her Island Fantasy. My heroine is a woman who’s just lost 30 pounds and is trying out her new body. She sets her sights on the groom’s brother, who she’s had a crush on for awhile, but he was in a long-term relationship. Now he’s not. They spend the week before the wedding exploring Hawaii–and each other.

I worry that some don’t convey that it’s erotic romance. What do you think?
Okay, images I like:
