I like the drum loop you have going - it almost has a tribal feel to it. The track was off to a good start but I feel like the track is lacking musicality which I think is pretty important in trance music. The breakdown is pretty cool. If you're going for an electro/dubstep feel, you gotta play more than one note and mix up the rhythm like JP mentioned. I'm not gonna yell at you though.
What JP is talking about is actually called "Call and Response"
and I think he explained it very nicely. One riff should ask a question and another one should answer. Your track kind of does the same thing from 4:40 to the end which is like a two minute outro. This is where your track should be climaxing. I would like to hear you build up to another solid melody.
