To make those parts look more accurate, take them to a belt sander and make them much thinner... Not the battery, but the other parts. You could also file a groove to make it look like the magnet and the hold down are separate as opposed to being one formed piece. They dont look bad, but I hate seeing the ebay ad that claims screen accurate.
EDIT:
Eh, looking at it again, if you sanded the bottom it would take too much away from the magnet, where the hold down is really what needs to be thinned out...
