Based on the name and the style of the song, I get the feeling of someone like a lonely bounty hunter/assassin wandering in life trying to fill a hole in his soul (hey, makes me think of Elektra).
The sounds you used are all really crisp and the mixing is pretty spot on. Just about everything has its place and it's not trying to overpower anything else. The only problem I hear with the choice of sounds is the higher pitched lead you use in the WUBWUBWUBWUB (it makes it come across as more BLUBLUBLUB instead of WUBWUBWUB). If you wanted to make it feel a little more dubstep I would suggest having a some heavy growling bass and a high pitched chorus that chimes in when the bass takes a break every other beat or something, oh like the bee drill you have that shows up 03:11. Although this is just my opinion, if it matches more with what you're trying to bring across I could simply be misunderstanding the song. I really like the spacey band saw thing I hear at around 02:40.
For song structure: It seems a bit too empty specifically at 00:49 up until 01:19. It's a really sweet atmosphere, but I think you can add a couple of pads or even some background strings like you used in the very next section after that. It still would give it an atmospheric setting without being too open.
Now you have a lot of good things going on here:
Your percussion is to be praised. I wish I could recreate a snare that sounds exactly like that, and even though it's loud it's not overpowering. You're also doing a good job bringing out a really sweet atmosphere. You're mixing the piano and string instruments really well with sum modern synths and dubstep type of things. I'd wager that this is more cinematic than dubstep. I like the transition you have at 01:17. I don't know if it's a percussion instrument or what, but I'd like to hear it more than once in the song.
Whew *swipes hand on forehead* Hope this helps. I enjoyed it and I think you should have higher than the 3 starts that I see you have right now. I voted a 5 to raise it up a little bit. Otherwise I think this song is a good 4 stars. Not a solid four unfortunately because I think it does need some work, but it does sound really good, don't get me wrong.
