This is just a bunch of high pitched noises followed by some lower pitch noises that make no sense in a composition together. Can't really say much else. Look up tutorials and try to get better.
Also, "dubstep is hard to do in LMMS so don't rate low if it sounds bad and cringy". Everybody will rate something low if it sounds bad and cringy. If even you are accepting that it sounds bad and cringy then why did you upload it in the first place?
Also (again), GD icon. I don't really have to explain myself here.
Hope you can get better at making music. If LMMS is bad for making dubstep then don't use it to make dubstep.
