I like the second. They're both really pretty, but I feel Rhi has more of an innocent aspect and that's how the girl looks like. Unless you're planning on making Rhi a bit of a seductress then you should go with the first. :)
I'm not one of your readers, so you probably don't even want my opinion... but I'd just like to say that from a bystander's position, the second one's girl looks kind of blurry. The first one seems more in focus, so I, personally, think it's the better choice.
And I'll get out of your hair and let your fans vote now. xD I was just bored and thought the blurriness should be mentioned. (:
