Yeah, it's pretty lame, we all know that. But it's a start. Assuming you're a beginner when it comes to music production.

From what I see you just used the default starter drum samples that come with FL Studio. I'd recommend getting better ones, but that's up to you (Most good quality samplepacks aren't free, so keep that in mind). There's also some random volume automation (Assuming it's assigned to the master volume slider), I don't know why would you want to do that, but get rid of it. The bass-synth thing in the background seems kinda random too, but honestly, I don't know what to say about it.

Good luck on improving. Won't be easy, but if you want good results, you need to work hard.

Good beat but needs some velocity control and melodies....
