I appreciate a good silent comic. One where words don't need to be exchanged to get the point across. Here you proved that you really can have a good comic without any dialogue.
Instead you use a great amount of well placed frames of Nightmare Moon looking at her long distance planet she use to call home and as if she actually regrets her actions and longs to be with her sister. It really is an emotional feeling to ones that understand the deeper context of the comic.
The art style of this is also very appealing to look at. It keeps the original style of the show but you added your own unique twist to it making it all the more unique.
*faepalm* i really dislike how everyone seems to think that nmm/luna was just waltzing around on the surface of the moon for a 1000 years when the show itself said she was sealed inside the moon... *sigh*
