Not bad.
Fluid animation, good premise. The pace is a little slow, try cutting out unnecessary pauses, and make it flow more.
Also, you NEED more than just one gunshot. Throw in a shuffling noise for the vampire walking, ambience like the soft bubbling of the pot in the background, the monster growl, crashes, footsteps, cartoony noises like whistles and clangs and what-not...
...and also, VOICES VOICE VOICES! Speech bubbles with an animation is a no-no!
Looking forward to seeing the finishes product!
