An intriguing concept...you handled it very well, taking the well-used "mask" metaphor and turning it into something new and different with the comparison to childhood's Halloween masks. I like doing that; finding new doors into old concepts.

Once again, I was rather thrown off by the rhythm. No random rhyming in this one, but the rhythm still seemed odd to me. It could be just me being weird; but you might want to show it to a couple of other people and see what they think.

Keep writing!
