Congratulations Angel! When composing for VG or film music, you really need to pay attention to the background story, the characters, setting (especially setting) and obviously the current scene you're in.
For yon "Urban Vampire" movie - I would personally strive for a very brooding, dark and gritty soundscape - so whip out your dark pads for sure (Orchestration can work too; but a hybrid with creepy pads would be pure win). Given that there's vampires, there will probably be seduction, maybe even some crude love scenes - so you'll want to consider makings the music for those parts feel more organic and soft - a brooding kind of soft - but you know what I mean . Then the horror stuff is really, really about timing the music to the scene, which means you've got to pay attention to each second to get the best result (similar with action scenes). Hopefully these basic tips will help keep your confidence up - and don't let the bad comments here pull you down.
