This looks pretty cool. I have a few tips:
1) I could tell that one of the boss's had actions set upon him every lil while, this is a cool detail, but I have a suggestion. Before playing one of the nodes, make sure that they aren't doing anything else (like already attacking, or on the ground, or dead). A simple way to do this is like this: if not PedIsPlaying(ped,"/Global/"..style.."/Default_KEY","Act/Anim/"..style..".act") then .....
2) Combine the fuckin' videos!
