Ahah. Love the little anime-type speech bubbles, but.. Maybe you should just stick to those. The voices were lacking, as I'm sure you've heard enough of by now.. I do like how you tried the b&w look, except there's too much light in your work to get that dramatic mood going. Darkness, a bit of raining would fit in much better. It's a glum film, after all.
The climax was lacking; A clinking sound to signify murder. Hm.
I'm having trouble figuring out what the background shadows were as well - Spirits of the undead? Randomness? Whatever they were, it was cute, heh. Good luck in future endeavours!
