there seems to be plenty of distortion on elements of your track. your most likely going into the red with channels to get things louder, and this would explain why your getting this.. put a limiter on you master track, and you will probably hear a positive difference, but distortion will still occur if your over pushing channels.. i personally think your arrangement of wubs is boring, and cliched, but hey i'm not a fan of that kind of dubstep really.. my mate did a track recently that used a really simple wub to good effect

almost anyone listening to your track will notice this, and you need to be instantly aware of something not sounding right. if you cannot your gonna have an uphill struggle. you can produce music to a fairly high standard these days with very little technical knowledge, if you have an ear that you can rely on..
i feel that if you got the ability to know what sounds good, you've got the potential to make great music...
constantly compare what your making to established artists, and doing this should expose flaws you need to work on. also study the same artists for how their tracks develop.
i have never had the money or anyone around me to give me music, or production lessons, and have had to study this way. i feel my productions are at an above average standard using this method. hope it might work for you too
get learning about the more technical aspects slowly and gradually introduce these things into your music to take you to the next level.. in the meantime get to grips with structure, and arrangement
people will begin making and progress their music in a variety of ways.. you just got to find a way that works for you.. it's easy to run into a dead end with a track unless you figure out method. i usually begin by creating what will most likely be the core of the track, then spend loads and loads of time finding an excess of synth sounds, samples, and whatever else i've got access to that might fit the project... now i'll experiment with the original 16-32 bar loop i made at the start with the extra bits I've sourced for the project and find a number of good possibilities for where the track might go, and then go about building a skeleton of a track. once you've done that and are happy, look to put some meat on the bones.
if your just starting out i would maybe look into using ableton.. the ability to develop ideas quickly, and general ease of getting to grips with its features could really help someone starting out.. the only other DAW that i've used, that comes close to doing that is reason 6.... the down side of reason is its closed plugins approach. massive let down... using both of these rewired is a great option IMO... check the production and technical forum for more in depth info..
FauxFurHoodie is right in what he says, but although my finished tracks are not prefect, i've got some good sounding stuff using just headphones. get some decent monitors that do not colour the sound in any way, but while your saving the pennies for them, i've got only good things to say about the KRK kns-6400 headphones as an option until then.
sorry for the long response, but just trying to maybe help you, out... the fact i'm as high as kite right now may have led me to ramble on a bit too much
peace, man, and good luck
