Well as far as the layout and any logos you created you can!!!, as long as you created the logo or images and they are not based on any other characters another company already owns.
For example if you used images from another website or the web that are not royalty free, or are copyright by someone else. Regardless of the creation you cannot copyright them if you used them to make something, like a template or some sorth of advertisement.
You are better off trying to create something on your own.
