I like the layout and design, but I think the text seems too cluttered and I think where you like, have the credits on two lines would look better if you could get them to one line each, because the space next to them looks kind of empty. Also, the colour of Itsuki's silhouette (that's what you call it, right?) is a little too brown to match.
Oh, and Itsuki is awesome, so that's definitely a plus. :3
