Oh sweet baby jesus, I love this. Labyrinth is one of my favorite movies ever (if not my favorite, period), and I love how you've stylized the characters. One of the reasons I adore Namesake is because it reminds me of Labyrinth, to an extent. The subtle colors really work here to separate the characters, and your lines, as always, are stunning.
I would love to see that. I think you'd be able to strike the right tone, easily. Speaking of which, did you hear about this prequel comic that's in the works? I really hope it goes better than that disaster of a "manga" they put out a couple years ago.
