Yeah, I think your main problem is your mix. The whole thing is so loud it gets distorted. Definitely pull those faders down.

I use FL too, by the way. It's a very good DAW, it will help you.

This song isn't very repetitive, it's just too long, and you need more instruments. I know you have sytrus, so use other presets, or make your own. Look up tutorials. Also, google some good sample packs too use for drums. There are plenty of free ones out there.
