Here is another entry for your challenge, Katty-chan! ^-^
I used the song "Are you the One" because it really fits for Yuna/Shuyin from final fantasy x-2.
I used the image of Yuna, and shuyin, then I added the one of Tidus and Yuna kissing, blending it in with the background,cause in that part they do dive in to a sea together.
It doesn't look as good as I wanted, but I tried.
