If this is ever going to get a shield that is double-sided, it's going to need copper 0 and copper 1 so that people can use it's PCB view as a template. Easy fix just put copper0 in a empty group called copper1. Could also use a black outline in the silkscreen group.
Good BB drawing though.
EDIT
There is something wrong with the copper contact pads. In Gerbv the holes are the same size as the pads, where as usually you see the smaller hole on a bigger pad.
