Definately the right, the " Ages 4 and Up" Needs to be equally distant in from the serial on the left to balance the top out.
I'd reduce the size of the first order trooper a little ,to bring his helmet below the name tab , also to reduce the FO trooper a little will make the image look a little less crouded.
Also try a darker colour for the figure area and name tab maybe more towards burgundy
Also try Avante Guarde BK font for the name tag, its about as close to the originals cards as you'll find
I've been doing custom cardbacks for many years and I have to say I like the direction you are going in.
Nice work, looking forward to seeing more
