*Nods* There's potential, but I'd recommend practicing a couple things. One is proper paragraph separation so that the viewer can read the text better, and the second is direct quotation. In other words, putting these (") (") around direct dialogue from a character in the story.
Although somewhat different, I've made something resembling long TG captions in my gallery, but even my story chapters have some of what I've just mentioned should you care to take a look.
A TG into this girl, maybe: Lisanna Strauss from the anime/manga Fairy Tail. If you look carefully, you might find an even cuter outfit to work with for the caption, such as this one. Just be sure to get permission if you go that route, unless you find a media-wide image. *Nods*
