Not bad for a first track at all.
You got good grip of layering and buildups. I agree with JAFARi, some variation might help. ...buit havbing said that, listen to any Avicii/Calvin Harris track ever and you find out they are not into heavy variations either.
...but that doesn't make it right either. Anyway! ... I'd work on a kick and bass. You're not overdoing the bass which is good, but the kick feels too mid-rangey and I think overall kick and bass could fit into themselves a bit more. Also these huge synth layers could use bit more reverb I guess. But still pretty solid start!
