Try some homework
Why was the girl in this movie shooting the vampires? vampires cant be killed by shooting them that only slows them down and whats with the sword battle stabbing them dosent kill them ether! the only ways to kill vampires is wood through the heart, dierect sunlight, decapiatation, Or to fight them off you could have added the people using a cross or holy water i understand you may have been baseing it on your own twists of rules of vampires but you could have kept the folklore rules to make it a bit more realistic.
