These two are such great opposites, it's not even funny --- "...So, she looks over to her husband, then sets it back down in her lap and says, 'Honey, this one's eating my popcorn.'"- Agent K ("Men in Black", 1997)
I can just hear rarity shreiking out her joy. As a comment though, Rarity's right eye seems off to me. The shape of it and the eyebrow seem like they're removed from the left eye and eyebrow. It looks a little like she's making two different expressions depending on which side you look at. Overall though, I love it and I love you and your artwork so much! Thank you for sharing it all with us, cuz we love it!!
I hope you never stop your art. The expressions are drawn with so much intent in mind. I see it, I know what is happening. Your art style is clear a precise and nothing is ever where it shouldn't be. And the lack of major shading just makes it look more stylistic, and bright, kind of like the show itself.
