Hey Fragmency,
Have to agree with Fishy re the muddiness. I think it might be caused by some rumble on the kicks not quite sitting right. On a production level, for me it doesn't change quick enough after the drop. When it does change around 1min 33 sec its cool but maybe you could give us it 16 or 32 bars earlier? Overall though its got a good structure, good tempo... improve the mix a little and it would come on heaps. Keep up the good work!
Peace
