Musically it's in key and melodic.....They could be talking about the reverb,but It sounds like you used a bit-crusher or dropped the sample rate on something...you need to roll off some high end on that, because there's this screeching noise....maybe side-chain the heavy reverb to your drums and compress it, push your drums forward...or just use less reverb
Where your melodic line plays in ...use an eq to dip that frequency range on the sample....
