It doesnt sound too messy to me.. but i wouldnt add anything else without taking things out You know?
The only thing i could recommend, being that I dont really do much in that genre, would be to add more changes throughout the track for the final draft. Take sounds out here and there, add sound effects here and there etc... take the drums out for a couple bars, or make them sound like they are in a tunnel for a couple bars.. Just little things like that can really turn a track out u know?
