You should credit AG+ for the artwork used. Other than that, this is great! You might want to add a glow or something more around the text so that it doesn't blend into the busyness of the background and become unreadable.
That's a very nice point you have there sir. I'm working making revisions on this piece. You're not the first one to make these suggestions. =] Honestly I'm a little disappointed in myself for not noticing how badly the text seemed to blend into the background before I uploaded it. In the revision of this image that detail will be corrected and full credit will be given to the original artist of the background artwork.
