Not a bad start at all! Heaps better than my first project was in FL. Showing much promise, sir. :]
I would definitely add a bassline to this. The lead synth covers a lot of ground and kind of acts like the bass for this piece, but it needs to have something more punching through the subs. Other than that, I would just recommend playing with the FL mixer, maybe EQ-ing some of those different lead voices so that they can really shine through individually and not sound so heaped together.
Other than that I love the beat, this song has nice form. Drums sound fantastic. I see you had some fun playing with different effects, and you did so in a way that really compliments the piece. Keep at it, bro!
