Decent!
Pacing could be better. You didn't really build any sufficient tension with the scarecrow or anything like that. The story told by the grandfather was probably the spookiest part. You should also work on your facial expressions - regardless of whether these guys are happy, afraid, or whatever, they all have the same vacant expression - save for the grandfather. The scarecrow's voice was also a bit silly.
Everything else was great, though. Your use of color and the palettes on offer here are very strong, and I thought the locales used were pretty cool and very iconic with Halloween.
