This is really nice work man, solid groove to it with some lovely ambient synth sounds.

Loved the dubtastic echo'd sweeping noise, think it would be better used a little more sparingly though.
Sound like that gets more impact from appearing less frequently IMO

Would look to vary the random filler noises, they are a little too predictable - always seem to appear at the same time and in the same place in the stereo field. Would be nicer to have them a little more random and organic, maybe vary the sound, vary the placement etc

Quality work mate.
