Nice song bro.
I really like the track overall: the melodies and the dubstep work really well and it flows nicely. I just feel as if the end is a bit rushed, that melody that lasts from 3:07 to the end is absolutely great, but I feel as if its constantly building up to something, then just before it reaches the tipping point it just fades into nothing. I'd love to hear another dub drop, you could probably build it up at 3:40 and have the song go on a bit longer, and I think from a listener's perspective the end just gets a bit dull and monotonous and needs some more dubstep love.
Thanks for the great track, keep doing what you do best. :)
