Seven nation army riff gets repetitive fast. Also, the bass notes are too distinct imo, sounds a bit too 'midi'. Maybe put some a bit of reverb on there, idk. The melodies over the top are pretty good, but most of the synths (wtf is that guitar) and the treble percussion samples, like, everything except the bass drum, just sound like really barely tweaked presets, sorry. I look forward to hearing more, keep it up.
