hey man i only recently started going in dubstep myself. there are two main problems with this track.. the drop isnt loud enough, and dubstep is all about the drop. this sounds nothing like dubstep.
the second problem is with those weird drums that kick in at some points, they are way too loud my meters peaked which means youre track has distorted parts that needs fixing, make sure everything is normalized to avoid that.

as a first try i think you did a very decent job, listen to more dubstep to learn there techniques i recommened sabrepulse and Skism

nice dude i usally dont listen to dubstep but this is kinda cool its like shpongle or ott meet dub step

I mean that when your kick drum comes in, the volume of the rest (primarily the lower end that is around the same as the kick) should go down so that your kick has some space. Also, when your snare or cymbals come in the volume of the rest (primarily the higher end that occupies the same or similar frequencies as the snare and cymbals) should go down. This can either be done through sidechain compression (there are plenty of great tutorials on how to do this on youtube) or by manually making it so that the volume of the rest of the track goes down just a bit and just while the drums are hitting. This can be heard in most electronic music (in particular house music where theres a kick every beat) by a sort of pulsing sound. hope this helps.

This is a good track. however, you need to work on some of the levels. The lead kind of sitar sound really dominates the mix and drowns out the first wobble bass that comes in. Also you need to duck your drums at points because there's times when they are buried in the mix. Also the second bass that comes in sounds more like a reese bass than a great wobble bass, maybe tone down some of the detuning. Also, when your synths cut off at about 2:00, I don't know whether you turn up the volume or what but it's way too loud and sounds muddy and distorted and it happens again at about 3:45. This is a really good first track. Nicely done.
