I like this and think its pretty good but i have some suggestions:
- either layer the main snare with something at a lower octave or modify it because it sounds pretty weird/out of place (you can leave it the same for the metro snare pattern)
- pitch the 808s, I got kind of bored listening to it, but its still a good drop
- implement more track variety. what i mean by this is try not to have your wave form come out like what it did for this track, do some different leads and such.
