Very nice effects and editing for first time around K-wix. But to restate what Norguard said, try messing more around with the framerates. Slower kills with a weapon like the shotgun, seeing the ragdoll effect, in slow motion would be a sight for all to enjoy.
And as for the clan-specific ones, I think that'd somthing cool to do. Have each member of the clan use their favorite weapon or something. EX: Me with shottie, you with FAMAS. Things like that mebbe.
