The title complements the poem really well, as it could be taken as " watch the crows" or " watch the night fall". Whichever the reader interprets :)
I like the alliteration that you've used it most of the lines and also how much you've displayed in nine syllables. The imagery is excellent and I can see it all clearly.
It must be very hard to express yourself in so little wording, but I though you did this really well. I loved it!
