That would be actually nice, referencing Stars, to get a feel of a whole epos that is connected. I always found it lacking that in the differetn seasons in the 90s anime there was no mentioning of the past villains and that there was no connection. So in SMEternal they could, as I mentioned above, depict Beryl/Metallia when it comes to the fall of the moon kingdom. Every SM fan knows the villains of the first season/arc, since it is the one that has been reproduced and retold most of all. And at the same time, they could make some forshadowing for Stars, just my mentioning the term "stars". This will excite us fans in both directions.
I wonder how Tadano's "failed" concept designs look, I bet even those must look cool. I still hope, the final designs will be a bit less childish. In the background of the composer's video we see Moon and Chibimoon and their limbs are longer then on the released designs, especially ChibiMoon looks less bulky.
I totally agree :-D
