The muskets sound great!
At one point in the video though, there's a moaning sound that seems to have come from 'Poltergeist' (somewhere around 40 - 50 secs) that has to go. And I can't hear any melee sounds at all - no clashing of swords and so on. Going by the demo, the vanilla sword clashing is very tinny; do you have links to any videos demonstrating better melee sounds?
Otherwise, good job!
