The percussion work at the beginning is cool, and sets a good tone.

I really like how unique the synths are in this track - they're pretty basic but they work really well together and are very crisp. It gives the track a really minimal/eerie feel.

The drop at 1:36 is a good idea, however I don't think the melody fits very much with the first section of the track. If you're going for a more bigroom feel, I would also kick up the BPM a bit. Definitely bring out the lead more though by making each note longer and adding some more reverb. I would also look into more bass and a different kick sample as well - both are essential elements to a good bigroom track.

I do like the melodies though, despite the fact that I don't think they coincide very well together. Definitely keep working on this one though, it's not too shabby so far!
