There's a couple notes out of place is that arp, it really distracts from the melody itself. That should be fixed. It's not a complete song for it lacks several things. This is what you have:
+Nice melody and intro
+Punchy kick and beat
+Synths that work together
But you're missing more than what you have.
-No bassline
-No buildup/breakdown
-No effects
-No variety
I'm not saying it's bad, it's just lacking. (: But you're on the bridge to success my friend! Take pointers and improve, no one gets it right first try, good job.

love the song!
