Not bad for a first version, but I don't quite like the shape of the book. I don't know, I have the impression that it should look more like some thick, epic tome, with sparkly bits of magic and stuff... Also, I don't like how it kind of bends. Why is that?
Yeah, like, keep the perspective but lose the curvature. Also, to make the book appear 'thicker' make the middle look bulkier. Open a book, one that was sewed(?), not glued(?), and see how it looks like. Also, lose the lines for the pages.
