Your quite right
This is professional. Very classy. Has some amazing stuff going on here. Break neck pace, fantastic melody. This is wonderful. A real great Dnb song.
My one complaint(and this is a stretch) would be that you over use the effect that makes it sound like its going underground. I suppose you start and end with it so it keeps it rounded but still. I just think yoy could have something a little bit more impactful, say like the song just instantly stops without any warning. That would be cool.
Anyway if you have time can you check out my stuff.
