Even though you're technically not clipping. I can hear distortion on the master. It could be your limiter.
To help your drums go clearly through the mix, you'll have to apply some sidechaining. The snare is kinda weak too, you prob just need to compress it a little and boost the body of it with EQ. You could also make it shorter and snappier.
This track also isn't very balanced, It's really heavy in the 200hz - 400hz range.
Other than that, the drum patterns are fine, the chords are fine and the synths (other than needing a bit of EQ) are fine. Just work on your mixing and get a spectrum analyzer, try 'Voxengo SPAN'.
