Looks like some one found slayer in the FL menu.
Its not a bad VST to use but try some effects on it man. Will help to get a REALISTIC feel. well... as close as you can get. But the hard drums i feel dont work well with what your doing.
It would help if you try to get a bass line rolling with your drums
some thing to keep it more alive you know?
but it seems your on your way for basic composer.
Its fun to Mess around with music don't you think?
