I got this in the mail recently. Yes… it’s a coloring book. But it is surprisingly interesting, as there’s all sorts of world information in it. It doesn’t 100% match up with what the comic established or what the cartoon might have done.
The art is pretty good though. Initially I had very low expectations based on the cover but the interior work is much better. I haven’t had a chance to scan all the pages but I hope to in the future.
Here’s few to look at, the one with the Emperor is my favorite. Enjoy!
