Ok, glad it wasn't just me. The only reason I was concerned was because both Harmy's and retail covers were a little wider than those Struzan covers.
I guess if I could suggest anything to people making custom covers is to make the covers as close to 10.5 inches as possible. Even if it is a little over, excess from either side can easily be cut. Making an image wider for those printing these out isn't really a possibility without losing detail and quality in the image.
