To add to blackryan's review.

Instrumentation: There are too many sounds that share the same wave type... i.e triangle, square, saw etc (what ever it is you used) and it's a bit difficult to follow what's going on. In other words, they clash.

Try replacing the bass with a sine wave. And the mid's with something else...

Melody: There is *too* much going on. The basis behind most successful tracks is that it has a relatively simple melody and is easy for the listener to follow, with simple chord progressions.

If you have a complex bass line - the synth melody is simple.
If you have a complex melody - the bass is simple.
You are trying to get listener's to focus on one point of the track, and everything else should compliment it.

There are also a lot of very dissonant chords being played which really isn't a good thing in any track. 1 or 2 yeah maybe,... to add tension, but it seems to be a common feature for this track.

The beat: Not bad, but it sits too far back in the mix and it's being dominated by the synths. The beat should sit at the forefront of the mix, with everything else behind it.

Track build: Some nice ideas,... But it was hard to know what was coming next. Successful tracks rely on a certain amount of predictability. Listener's subconsciously analyse your track and reference it to EVERYTHING they have ever listened to and feel comfortable knowing what's coming next. Your job as a producer is to make subtle changes that the listener isn't even aware of.

Most tracks follow a certain "pattern" when it comes to structure and the following is an example:
A = Intro
B = Verse
C = Chorus
D = Bridge
E = Outro

A,B,C,B,C,D,C,C,E
A,C,B,C,B,D,C,E
A,B,D,C,B,D,C,B,D,C,C,E

Your track goes like this:

A,B,C,D,E,F,G,H,I,J etc.... There is no real "structure" to it.

The mix: I could write an essay on this subject and not cover everything, but I would suggest reading some articles about it :)

Overall though, I think you need more practice. Watch some tutorials on YouTube for FL studio (there are hundreds, if not, thousands of them), learn MORE about your craft, chord progressions, melody making, track structure, beat making etc

Practice makes perfect :)

Keep at it mate!

sorry i cannot think of anything good i can say about this.

Edit - sorry i was a bit vague I know. I think you need to improve on the composition of the track, the flow of the track, the choice of instrumentation.
