Where to start.
Well, to begin with, you have no bass, you have no melody. All it is, is you throwing a sample down and...that's it.
You didn't even attempt to cut the sample by its self so it doesn't overlap.
You seem like you're 10 so I'll just recommend you look for better drum samples and use them to your advantage. The FL Studio standard kicks, snares, claps, and hats just don't cut it. At all. For any type of production.
You need to learn something about chords and key relations before you even think about opening up the piano roll. None of your "notes" make any type of sense and it's just painful to listen to.
Take the time, learn about music production and come back.
Please, for the sake of humanity.
