I think the song need some more low frequencies, especially the synths.

But it's nice, I also did some shit with dubstep, keep it up.

overall, good, i dont feel the drop is powerfull enough, some silence just before it will work, and the same synth patterns in the drop start to get boring at the second part. Try some creativity with fun samples. the part @ 2:00 brings some variety. If i you could build for a drop as you did it in outro, it will sound nice

If you would like, please review my music
