I'm very confused. Some of the photos show carriers being berthed at Pearl, which suggests that the diorama is depicted a few days before the attack. But all the other ships look exactly as they did on Dec 7, and one of the photos even says it depicts how it looked right before the attack.
What gives? Is it more than one diorama? Are the ships moveable? Or is it a VERY major oversight?
Other than that, yes, it is very well done and nice to look at.
