At first, I thought it was Zelda, but then I saw the title, and I quickly got much more excited. EarthBound is probably my favorite game EVER, and Mother was an enjoyable, if somewhat difficult, predecessor.
Overall, I like what you've done here. It's not quite the same as I always pictured Magicant (if I were standing *in* it, as opposed to looking down *on* it) but it's fitting. And good job on the "fuzziness" that comes with distance, but you may also want to consider thinning out the lines on further back objects, too.
