I almost missed the fact that other instruments were present. The hi-hat, kick and bass were almost unnoticeable. The piano line (Nexus?) was pleasant though. Regarding the repetition: at the trap 'drop' you're going for, it may be a good idea to do a lot less with the piano, or remove it entirely so the other instruments have enough room to breathe. Like, chord stabs or something, just enough to float over the hi-hats and bass. Also the atmospheric pad you have from 1:13 on is dissonant enough, but it really does clash against the lilting piano.
As far as mixing goes, I agree with Smooth4lyfe: definitely lower the piano a bit and raise everything else. And look up 'sidechain ducking', it's quite a useful tool.
Keep making more, though! I look forward to more! :3
