I have some prints I have done that are on aluminum. They look very bright and vibrant. I imagine the effect on copper is something similar. With that being said, none of the artwork for any of the pieces shown is really winning me over.
I'd get the G1 Prime if it was available here. Same with those little mini G1 copper figures that were shown a little while ago.
