1) Assuming you are using Photoshop, move the brushed metal layer to the bottom. The way you have it between the text layer and the borders is kind of strange looking.
2) Get a better brushed metal texture. The one you're using looks like a small jpg stretched to fit the cover template, and you're losing some detail in the top of the image. If you can't find a higher resolution one, it's easy as hell to make your own using Photoshop's native filters, and using some simple brushing techniques to make it look all destroyed like that.
But good stuff, so far. Keep it up.
