I've tried this because i love making melodies it came out a little too hectic probably because the tempo was around 160 :P.
Definitely turn down the delay on that middle synth, i can see what you were trying to go for, but because of the high delay it sounds as if the notes aren't corresponding with the chords because the delay is overlapping.
Marimba was sick, great idea, where did you get it from btw, sounded so realistic.
Loving the Electro-ish bassline.
5/5 9/10 Sick stuff man
I suggest you start doing more stuff with vocals if you want to get signed. Although this is awesome no one is going to sign you with this kind of stuff, but if you add vocals to it then you are guaranteed a contract.
