Not dubstep did someone say? I call bull. Just because the wobbles are reesy doesn't mean it ain't dubstep.
Now, I would say the structuring of this song could use some work, particularly where the perc comes in and we think we're going to get a drop, but we continue the verse.
You've done some really cool things with your basses. I could compress the different ones during the drop so they're about the same loudness as one another. The disparities there are a little distracting.
Also take care that your basses are not getting in the way of one another. On your later verses, I can hear the frequencies struggling to come to the fore.
Some things that are lacking here, solid transitions, as in the noises themselves, crashes. That's more or less stock to the genre. I would probably actually not use a reverbed sine bass just for how muddy they tend to sound.
But your melodic content and idea overall are great. Enjoyed the listen.
Thanks for coming out to NGUAC!
