The melody sounds like random notes and chords, learning some basic music theory (scales, chords, keys) will help you write a more cohesive and memorable melody. The sample leading into the drop is the wrong tempo, and that's important, since the listener will need the sample to know the exact moment the beat drops, so either stretch it so it's in time, or use a different sample.
The drop "bass" has no actual bass and it's in the wrong key. Layering another bass under it, with more actual low end, and EQing it, will help a little, but it's just not a very interesting sound because there's no movement, just the same noise for the entire drop. Break it up with some other sounds, to give it more interesting rhythms.
Finally, get rid of the limiter on the master channel, PLEASE, it just makes everything sound bad. Find some tutorials for mastering if you want it to be loud, otherwise, just turn down the volume.
