I'm mostly a story-writer and certainly no expert on poetry, so I read this for the tale it tells, the imagery it conjurs, and the feelings it produces. In those respects, it works very well.
i find your rhyme scheme interesting, though i'm not personally big on rhymes. but i'm wondering if you changed up your rhythm purposely? it catches the reader off guard, a little. if it is intentional, you might want to add some more oomph to your imagery, to match the shock of it. if not, you might consider smoothing the rhythm out. but your piece definitely evokes a haunted feeling. nice work!
