This track has a lot of potential. I agree that it could use a peak where it gets really crazy, a climax of sorts. Just keep layering new parts and automate synth paramaters like nuts. Also, one of the melodies just switches back and forth between two notes. It felt like it needed to have more melody around the scale you're using other than just those two notes. I turned on my synth and started playing around with melodies, got some good stuff using this scale:
D, F, A, A#, Db
Good luck and happy trancing.
