I actually like the jagged lines in the background
They look faintly like swords, or blades. Maybe putting a border around the image?
EDIT: It looks like the pink bar with the font goes from behind her to in front of her right arm. It's just my personal opinion, but I would put it behind.
Another personal opinion/idea (hehe...): You're screenname is MissChoco, but I see you like to use the title "Moon Child" as well. Maybe making the text for "MissChoco" larger, while putting a smaller "Moon Child" beneath or above it. I think that would making a stronger focus on which one to look at.
