That bass drop at the beginning is great. This could be in a film. If I'm nitpicking - I think the cymbals could have some more space or some reverb, maybe a little more air on the top end. It's gimmicky, but I wonder how they would sound reversed, then add reverb, then reverse again so there's a build up into the cymbal hits? The snare could have a little more crack on the top end as well - you could even layer another snare sample. I also think you could go even bigger with the kick sound. This is just nitpicking though to try to juice it even more. It sounds great.
