I really enjoyed the mix. Despite the kick and snare from basic pack of fl and hi hat a little bit too loud, I really love what's in there. It could definitly be a nice dubstep mix.
From 2:07 until the end, it is awesome and well made. Need a little bit of fill-in drums and this is ready to go.
The start feel a little bit quiet and needs more synth.
Seriously this is nice work. If you need help PM me. We could collab or I could fill you with very good advice.
