I like how you have the background colour that shade of brown instead of just white, and how you've added little areas of colour, it makes it more interesting and eye catching then other story boards or commics.
on the 1 image where she rips him apart there could be a howl or some blood dripping of his arm or twitching of his arm while dying... i think it would ad that little more intensity u want to that little image...
