There can be some improvements though.
This opening scene is almost the same scene as the original Bloodsucker, which you even copied the title from. Unfortunately for you, spacejelly did much much better.
Next time you should try animating your own ideas and charactors.
dude its a tribute to that animation it say's tribute right on the title
it was good needs a bit of work but keep doing what your doing 5/5 7/10
looks pretty good hope to see full version soon! < \
