The build-up is very good.
The side-chaining effect is welcomed, but maybe it's a bit TOO much towards the middle.
The volume of the melody also gets a bit too high (losing the quality of the sound) in the middle as well.
Very interesting test. If you'd keep that main melody after this build-up and put a good beat and other layers this would be a good trance song, imo.
I didn't listen to your previous test, but don't let go of this idea ^__^.
