You really build up the mood! I like the style of light and color, how it's not the traditional 'darkness', but still a kind of cozy setting for a nightmare, creepy, but in an atmospheric and entertaining kind of way. Animation's smooth, the background spooks subtle; it all flows nicely, though the wordless communication between characters isn't always the clearest - gets clearer towards the end though, not so much ambiguity as to what each expression might imply. Nice work!
